Is there a reason why? I was ready to but, but price went up $9!** A: You may have noticed that price changes happen constantly on Amazon. I used to think it had to do with stock on hand. I now think they are using an algorithm that does “dynamic pricing”, like concert tickets sellers use. Who knows what parameters they use. With Ticketmaster, the faster tickets are sold, the more the price goes up. Supply and demand principles. To Ticketmaster’s credit, at least they are transparent about their use of it, and even have link to an explanation of their use of it on their website. When using Amazon, unless it is something I need right away, I usually save it to a list, adding a note with the date and the then-current price, and also put the item in my cart, then move it to the “save for later” list on the cart page. When you do this, every time you look at your cart, it will tell you which items on that list have had a price change, up or down, and the amount. I then wait for the price to go down. A couple of years ago, I saved over $130 on a larger ticket item. That was definitely worth the wait. Also, if you are a Prime member, you must realize the free shipping isn’t really free. A little of the price is due to this, especially on cheaper items. It’s like buying a bottle of aspirin at a corner store cost more than at a drug store, which costs more than at a big box store. You pay for convenience. Even though Amazon denies that it has implemented one the more insidious aspects of dynamic pricing: different customers seeing & being charged different prices for the exact same product, based upon the analysis of all sorts on data, collected by aggregation services who data-mine the internet for such information (thanks a lot, Facebook), even including psychological theories regarding shopping and buying behaviors. Or just simply: the higher your income (which can be determined by credit bureau report/credit card companies—which, by the way, if you have a credit card, at some point you voluntarily gave them your income info, which they can and do share, for a fee), the higher the price that will be offered to you. Studies show most people never even realize that this is happening, and the algorithms also determine your “price tolerance”, and adjusts the pricing based on what the program believes you might pay for an item. If you are not familiar with the concept and usage of “Dynamic Pricing”, do yourself a favor, look it up and educate yourself about it (from a legitimate, reputable & reliable news source, please). It is a very interesting concept, and may even get you thinking about how much and what type of Federal regulation of the internet is needed. **Q: Is this as pictured or the ones with a 24 on the front which I won't order** A: This is NOT as pictured, it has a 24 front and center — which I did not want either but realized too late to return!! **Q: I want the top and bottom strip to be long which crest white strip should I get?** A: For any of the Crest Whitestrips the bottom will be shorter than the top.

I get professional cleanings every 3 months, and I’m not exaggerating when I say my teeth look whiter right now than they do after a fresh dental cleaning.A few things that stood out:Fast results — I saw a difference within just a few days, which lines up with claims that results can start quicklyNo sensitivity (for me) — I was expecting some, but nothing at allThey actually stay in place — I can talk, drink water, move around without them slippingProfessional-level results at home — honestly feels like I skipped a $400 whitening treatmentI’ve tried whitening toothpastes, trays, all of it… nothing has come close to this.If you’re on the fence, just try them. I wish I had done this sooner.These aren’t just “slightly better” — they’re legit next-level whitening. I’m already planning to keep these in my routine going forward. ### ⭐⭐⭐⭐⭐ THE best crest whitestrips I've ever tried *by on Reviewed in the United States February 15, 2025* These are without a doubt the most whitening/brightening whitestrips I've ever used. The strips are so uniform and the whitening ingredients are so well spread onto the strips it's crystal clear.I've been using crest whitestrips for 14-15 years now. I started all the way back before the non-slip was even invented and you'd have to just kinda bite down on your teeth to prevent them from sliding around. They've been VERY effective in the past, which is why I've continued to use them throughout the years, but this pack right here is the most effective one I've ever used. I'm only halfway done with the set but my teeth are OUTLANDISHLY white. I started getting compliments from coworkers my 3rd day in. I did some research after buying them because I wanted to know what made these different, and it turns out it has the highest hydrogen peroxide concentration from all other strips out there. Their other strips contain 3.5%, 8% etc, this one's supplying the highest concentration you can get. I will say, if you're new to whitestrips they work by oxidizing the surface of the tooth to remove the stains soaked into the teeth. It's enamal safe, but you'll notice sensitivity. By day 5 I had to go out and get some sensodyne . If you're having sensitivity issues, I recommend getting sensydne and when you go to brush your teeth, spit out the toothpaste, not rinse. When you go to bed, brush softly and spit out the toothpaste, go right to bed and the floride toothpaste will help stick to your teeth and stop that sensitivity. ### ⭐⭐⭐⭐⭐ Should’ve just gotten this from the beginning. It really works! *by on Reviewed in the United States June 9, 2025* I’ve had decades of smoking and coffee drinking, my teeth were yellowing and I was getting self-conscious of my smile. I tried everything else: whitening toothpaste, gel that goes in a tray in your mouth with a light, and several other, cheaper whitening strips. By the time I add all those products up, I would’ve saved money if I had just taken the plunge and gotten these. After the 2nd treatment I noticed a difference. I’m on treatment 6 now, and continue to actually be able to see the difference this is making. I had a little teeth sensitivity, but not bad at all. I’ve been told that genetically, I have good teeth. Never a cavity or any issues, so I’m assuming that plays a part in not really having sensitivity with these. I have never used these strips before so I am cutting them in half long ways, to get more treatments out of them. I also prefer how it fits on my teeth that way. When I apply them I do run my finger over each tooth to make sure everything is fully covered. I am so glad I finally spent the money to try these and have learned my lesson. No more cheap, knock off stuff for teeth whitening, I will stay with Crest white strips from now on! ## Frequently Bought Together - Crest 3D Whitestrips, Supreme Flexfit, Teeth Whitening Strip Kit, 42 Strips (21 Treatments) - Crest 3D White Luxe Whitestrip Teeth Whitening Kit, Glamorous White, 14 Treatments( Each with 1 Upper/ 1 Lower), 28 Strips - Crest 3DWhitestrips Sensitive + LED Light Teeth Whitening Kit, 14 Treatments, Gently Removes 20 Years of Stains --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/33132589-3dwhitestrips-age-renew-at-home-teeth-whitening-kit-21-treatments](https://www.desertcart.tn/products/33132589-3dwhitestrips-age-renew-at-home-teeth-whitening-kit-21-treatments) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-30*
