Just was wondering recently about how far to go on making good on buy/sell transactions. Here are some examples of recent transactions: 1. Sold a 70-210 canon lens on another board. I didn't insure it, but did require signature. The post office delivered it without a signature, and the buyer claimed he never got it. It was "only" $150 (i.e. not $800 or something) and I refunded the entire purchase, because I felt it was my responsibility to ship it properly (since then, I've never not insured. btw -- the post office would only reimburse me the cost of the signature required service, or $2.10, and only if I filed the right paperwork). 2. Sold a CV75/2.5 lens. Listed it in the description as "in good but used condition" but forgot to select the drop down on the fredmiranda site for condition. The default is "10. like new condition" and that's what the buyer read. When the buyer got it, he complained, because it had scuffs (understandable). I gave him the option to return it, or a reduction. The buyer chose the reduction. 3. Sold a lens in person (face to face) with a buyer I connected with on a board, but the buyer e-mailed me shortly afterward with an issue with the lens that I hadn't noticed. I believed they were being truthful, and it was just something that was missed by both parties. I did mark the lens "like new" because I thought it was. I gave them a price adjustment and, in turn, they gave me a positive review from the transaction. 4. Had a buyer for a low-priced item. It was my first cross-border shipping (to Canada), and I made a BIG mistake, sending it UPS (don't EVER use UPS across the border!), who decided they wanted to hold it up for $35 in fees for a $50 item. The buyer abandoned the item. UPS wanted $35 to send it back home to me, so I abandoned it, too. The buyer (graciously) volunteered not to ask for a refund and I was out the item (though UPS got a little gift). IMO, the buyer went above and beyond here. Has anyone else had transactions like this where you were in a situation to "make good" on a transaction? What did you do? When is it your responsibility vs. the buyers (or vice versa, if you are the buyer). My opinion is that it is the seller's responsibility to deliver the item up to the point of signature. If the item doesn't arrive for signature, then it's up to the seller to refund and seek the insurance claim. The moment the item is signed for, it's the buyer's item, unless they have an issue. What do others think?
