My personal opinion is that, as a buyer, there is nothing protecting you and there is always some chance you’ll lose.
I try and only buy from people who’ve been around awhile and try and message them enough to get some sense of who they are. After that, if I’m comfortable with them I generally send cash overnight. I haven’t been wrong yet but I’ve walked away from a few deals.
The option that provides buyers the very best chance not to lose is a credit card. The protection that is offered by major credit card companies is far superior to PayPal and the runaround they give you when you make a claim.
Several years ago I purchased a small $40 item and paid using PayPal (which then gets charged to my credit card). The seller sent a tracked package containing a 50 cent key chain and nothing else, and was totally unresponsive to any inquiry. When I made a claim through PayPal they took over 6 months to “investigate” and found for the seller because they had sent a tracked package to my address. It didn’t seem to matter to them that I had photographed the package with the tracking number showing the contents was not what was ordered. As far as PayPal was concerned, after their prolonged half year investigation, I got a package from the seller so I was lying and had to pay.
I ended up having to go to the CC company and contest the PayPal charge. The CC company looked at my evidence and the correspondence with both PayPal and the seller and in less than 10 days found I was right and removed the PayPal charge.
I did get a letter from PayPal telling me that in the future I should contact them first to resolve any dispute instead of my CC company ( which of course I had, but they didn’t seem to know it, or perhaps just pretended not to?). Other than that nothing further was said by PayPal. My account is still active.
I still use PayPal for very small transactions but avoid them for anything over $50. If a seller doesn’t take a CC I usually pass. Some sellers charge a fee to use the card which I weigh when deciding to purchase. I pass on those sales more often than not, but if it’s something I really want I look upon that fee as paying for protection to actually get what I’m paying for.
Over the years I have only had a dozen or so problems with CC’s. Since I keep good documentation on things I buy, I have never had a problem resolving any dispute over charges with them. As far as I am concerned a CC (NOT a Debit Card) is the safest for a buyer.
