Well, I have been using Ebay to both buy & sell for almost 10 years now. It has only been in the last year or so that I have had any problems.
About this time last year, I purchased a stroller set there for my daughter, but the auction got flagged by ebay. This had happened once before on a purchase of mine, but in that case the seller was doing nothing wrong and the sale completed just fine, so I was not overly concerned. After, being assured by the stoller seller that shipping would occur in a timely manner and the sale was legit, I asked for a tracking number to be e-mailed to me when item shipped. Seller agreed. Then the problems started. She kept trying to put me off. You see a complaint has to be filed within a certain time period after auction. I gave her 3 days to comply, then I reported to both Ebay & paypal. It took a month or so but I got my money back.
A few months ago, I sold 2 items within a week of each other. Sent them right out. Buyers complained they didn't get them. They were only a few dollars each. I refunded, but was a bit suspicious that they may have actually received items, but knew anyone with 100% positive feedback would refund small purchases without issue.
Here's where they got me though. I ordered magazine subscriptions this spring. I have done so in the past and mags always came. Listing said, mags should start arriving in 6-8 weeks, the seller had plenty of positive feedback. Mags never came. By the time I realized that they were overdue. Seller had closed up shop and it was too late to get help from Ebay or Paypal. Ebay has suspended sellers account, but I bet they will be back under a new name.
I just wanted to warn any Gatherites who also frequent Ebay, to keep a close eye on any similar purchases they make. I got lax and it cost me, don't make my mistake.
