2x2 Self Sealing ?

I bought a batch of these from Tradewinds coin supply. I really like the idea of no staples. But they are kind of expesive compared to the regular 2x2's. They are neater and stack nicely in the box.

Anyone know of a cheap source for these? A stack of 50 cost me about $6 each. I have a lot of coins that are not valuable, I just think they are nice coins but saving them in these self stick 2'x2's is going to mean some of the cardboard holders are worth more then the coin I put in it.

Any idea's?
