Since a lot of you folks do Carhartt, I thought you might like to know.
http://dungarees.net/These guys have a store just across the river from me. Last month, after searching threads on APS, I decided my next pair of jeans would be Carhartts. I got a pair from Dungarees, in St. Charles, and only wore them on casual Friday. I didn't exactly abuse them. Nonetheless, holes appeared, just above the stitching for the back pockets. Since then, I've only worn them outside of work, since my untucked shirt-tail covers the holes. And then a big rip appeared in the crotch.
I had no receipt for them, but I thought I'd try to exchange them, anyway. The guys at Dungarees apologized for the inconvenience, and were glad to give me a new pair. They hadn't any in my size, so they offered to call me when they had some, or give me a gift card.
They also said they had some issues with the jeans with brown pocket linings, which might explain why they took them back so readily. Either way, they're a pleasure to do business with. They also have discount items that are marked with the wrong size, etc. I don't know if you can get those online.
