I purchase luxury Grand Suites 600TC Silk and Cotton Sheets item # G13529 from ShopNBC for $87.57. After only 6 months, they have completely wore out. The pocket seams on the fitted sheets have ripped out because the fabric is so thin. The top sheet's hems are all frayed out, and the fabric is so thin that rips 6 inches long have appeared. Customer service says they only accept returns for the first 30 days, even if the quality is poor. Cheap sheets last longer than 6 months, and these weren't cheap. I think a company that sells an inferior product should refund the customer's money and discontinue selling the product. These sheets are still for sell, however, now there are many comments much like mine concerning the poor quality.
