Don't really know as I don't see there, but there is this one thing I bought from ebay and it came really late. I requested the refund as I didn't get the package within the date he has given me. 2 weeks pass by I get the item. I contact the guy saying that I got it and that I would now like to pay for it. So I say to him that I will buy another item, but he should not ship it to me because I got the refund for the first one. He said great, thanks for being honest with us. Few weeks later I get the same item to my address haha I tried to be fair to him, but the guy sent me 2 items for a price of one.
that is very nice of you for doing that. 99.9% of people wouldn't bother, people like you are what make ebayers like me enjoy what we do. Many ebayers (myself included) try to treat them special to know how much they're appreciated.
-I've sent a random free item to them related to whatever they purchased if i have something I don't mind gifting
-agreed on partial refund, due to good buyer experience decide to up it to a complete refund as a surprise
-offered a strong discount on anything they want that's listed, going as far as providing it to them at cost and/or shipping
-in the event of buying something people want more of (such as collectable niches), add in extra items to the box that i think they'll like. I once raised the value of a purchase from 15 for a single item, to 200+ for a box of items, because the buyer was super polite and kind and it was near christmas so I wanted it to be a nice gift.
I've made a few long term customers this way over the years, a portion of which wind up becoming a non-ebay relationship where they contact me directly, I give them large breaks in price due to the level of repeated business and removal of ebay platform fees.
for future reference though, ebayers dealing with medium to large volume may completely forget/overlook/miss the arrangement between you two, and ESPECIALLY if they have a dropshipping or automated workflow set up so they dont manually deal with purchase and transactions
Next time I would recommend sending the payment back through paypal to avoid this issue from occuring, not including bay in the system so there's no issue of the system thinking you just bought a second item
but yeah, being a friendly, overly polite and unexpectedly good experience is a great method to increase your sales, loyal fan base, and inventory movement. that ultimately increases your revenue despite the loss on gifted items
