Tradesy is very expensive but I'm making more sales there than ebay lately. The only problem I've had is that they returned a bag to me, claiming my measurements were off, but they weren't. Quite a few tpfers have had bags returned to them by Tradesy for made up reasons.
The heaviest bag I ever had was the Legacy medium Lily. I found it on ebay, and the minute I unpacked it, I knew I could never carry it. I resold and just kept my fingers crossed that the buyer wouldn't return it because of the weight. Several years ago, I had a 40% (I think, or was it 30%?) coupon because of a class action settlement with
Coach. I bought a Carrie and the dragonfly duffle with the coupon, and ended up returning both because of the weight. Even with the coupon, it was the most I ever spent at Coach in one trip.
