I got the Holiday Patchwork duffle for Christmas and the gold patch on the front is discoloring already. I would understand if it were on the back, where it would rub against my body, but on the front. I watch how I wear my bags, and I always wear the logo, on the outside. Is this normal wear? Is this how the gold fabric usually is on Coach products? The other side is still perfect. It came from Coach.com, do you think I should exchange it, or will it just happen again? If I exchange it, does anyone know about how long it will take?
