i've been collecting them too! I have found that ACMoore wants $3.99 compared to Michaels $5.99. Michaels is usually cheaper around here. If I am shopping with a coupon and can't find anything else, I will usually buy a paper pad. I also only buy double sided because if I don't like one side, I usually do the other. I didn't know they made 8x8....will have to check into that.
