Query: Last third of these in the box were defective

I ordered this box of 100 sheet protectors in February 2010 at a price about 30 percent off the retail value.The first two thirds of these were perfect.I have discovered (a year after I received them) that the last third of these (about 30 or so) are defective along the left seam, such that you cannot fit a regular sheet of paper inside them without creasing/wrinkling the page.So I guess you get what you pay for --when the product is significantly discounted. I paid about two-thirds of the retail price, and got about two-thirds of a box of fully-usable sheet protectors.I can still use these remaining defective-seam sheet protectors for items that are not 8.5 by 11 inches in size.If you are ordering a box of 100 of these sheet protectors because you need 100 of them for a special project, be wary that not all of them may fit regular sheets or paper.
