I used to buy preloved bags but honestly unless it's a great deal I'd rather have a new one. I've seen a lot of Coach for 15-30% of original price. Only the really high end bags (LV and up) seem to keep any value whatsoever. LAMB does seem to go for very little on eBay. I tried to sell a few Coach and got no nibbles whatsoever (ones I bought preloved anyways) and I ended up giving them to charity.
