I was in Costco in Richmond today to buy oil and noticed they had a 15 pack of microfibre towels for $14.69.They were 14"x14" and made by a company called Superex.Has anyone tried these?Sounds like a pretty good deal.I'm there every week so if anyone has some good words I'll pick some up.I've never used any kind of microfiber before,so I am a little hesitant.
