Well.. I bought a white speedy 30 on eBay last year and it had the peachy discoloration on the pocket. My SA gave me a brand new speedy on the spot. She said due to that dye lot, the whole bag would get affected eventually.
Adeener, when you get your bag back, keep a close eye on the rest of the canvas.. if you see any yellowing at all, bring it back and insist on a store credit or a brand new speedy! It's crazy that different stores have different policies regarding this COMMON and well known defect!
LVobssesed, I would fight for your money back! That is crazy!!! I can't believe they charged you??! They should have been apologizing for your trouble and given you a new bag, or at the very least a FREE repair! UGH!!!
