I order scrapbooking items online frequently and find that prices for the same item vary from one store to the next. I buy on ebay, also, but have found that many times ebay prices go higher than buying from an online site.
Have you found a good scrapbooking site for general scrap supplies that has good prices? Shipping prices should be low, too.

This store isn’t too bad on shipping.
