Can they be used to actually mail?

The Penguin Stamp pays the difference between the First Class one ounce rate (currently 47c) and two ounce rate (currently 68c). You can use the Penguin Stamp to mail letters if you figure it as a 21c stamp.

Can these only be used in addition to a 44 cent stamp?

This stamp is equal to 21 cents. You need to have additional postage to mail a postcard or letter.

what is the value of this stamp? i think it used to be 22 or 21 cents and now when i search for additional ounce cost online it says 15 cents!

Correct, 15cts, it is like a Forever Stamp the Value will always be good for paying 1 additional ounce. 3 stamps 3 ounces. etc..

So if I understand this, rather than pay $4 for $4 of postage at the post office... I can buy $4 worth of postage here for almost $10?

The extra price is for convenience for many of our buyers.
