Look on ebay, from what I see about $12 for 100 was commo. I bought some 4" for $2+shipping, got400 for $20 something. But have not seen them that cheep since. Personally, I wouldnt think it would be worth the tiime to cut them for that little bit. Hopeyou do well with this, cutting those little squares is not my idea of fun, thats why I bought them when theywereso cheep.
