Listed bag at $169.99 with $199.99 BIN with free insured ship. I'm top rated seller with 646 100% feedback. Mentioned the Ebay/Microsoft Bing cashback program in listing (currently @ 10%). Buyer bought bag @ BIN price. Paid for the bag this morning. Few minutes ago, buyer emailed and said she found same bag cheaper with another seller ($164.99) and asked me for a partial refund. I gave her a little speech on sellers set their own prices on their items, that most will not let buyers back out because they found a better deal after they bid/paid for the item. That most sellers do their research on prices before you buy. I told her I can do a one-time courtesy partial refund as she is a new buyer - she would get difference of the other's seller price and what she is getting bag from me w/ the cashback promo ($15.01 partial refund). I also gave her the option to back out of transaction as I don't want to force someone to buy from me if they are not happy with their purchase. This buyer is not new. Been on Ebay since 2004 with 350 feedbacks. What you ladies think ? Am I offering buyer a fair deal ?
