Have you ever been dinged by negative feedback and if so did it hurt your sales for a while?

I've gotten 1 (out of 950 plus) and the details are in the paragraph below which I copied and pasted from
an earlier thread in this forum.

Years ago I received a negative feedback for a Princess House item I sold. The buyer said it wasn't Princess House though it was shipped in its original PH box and had the PH pattern in the glass. That negative feedback stayed with me for 1 solid year until it cleared out. At that time I was able to give the buyer negative feedback as well. Now, 7 years later, my feedback has gone from 100 or so (then) to almost 1,000 now (not a lot, but I'm happy with it). Meanwhile the person who left me the negative STILL has 10 feedback and they are ALL as a buyer.

While it didn't hurt my business, it hung around for a year before going away. Fortunately, those buyers who do look at your profile for feedback results take this with a grain of salt and for the most part, most of them won't go through each of 10 or more pages to find the negative.  Update on the other person's feedback: It went from 10 to 11. The person bought one item this year and actually got feedback from the seller.

Are brass decorative items doing well for anyone?

Are Beanie Babies still collectible?

Several years ago I sold a batch of 50 for $75 to one of the members here. I've forgotten his name, but am sure I could find it by looking through the threads on Beanies.

I haven't gotten anyone's collection in years now, but when I did only the bears did well for me and that might have been $3 to $10 each. The rest, $1 each and finally gave them away to kids when parents made a purchase of something else. The goodwill was worth as much (if not more) as the sales.

How do eBay sellers of store cards (like Home Depot) make any money on them?

I have seen Home Depot cards with a value of $200 sell on eBay for $180 as an example.  The only thing I can think is that the seller of this card bought it from some hard-up person and gave THAT person maybe $50 to $100 for it and then is flipping it on eBay.

OR....person "A" buys it with a credit card for $200 (defaults on the cc payment) and sells the card for cash to person "B" for $100 and THEN person "B" sells it for $180 on eBay. Something might go wrong somewhere along that line for the crooks trying it.
