Same here. I've bought and sold quite a bit on Ebay over the years and never have had a problem either.
Always make sure you read the feedback of the seller first before buying/bidding. On the larger purchases, I will often contact them beforehand and ask them a question or two for extra reassurement. Ebay now has protection plans which will cover your purchase if something goes wrong,
About our buyer protection programs
When you setup a PayPal account, the funds are simply transferred from your account to theirs or vice versa. This makes it so there are no credit card numbers that get shared or anything like that on either end.
When it comes to shipping, always read their particular shipping policy & included shipping cost to mail the item so that you know what you'll be paying and how long to expect to recieve it. Most the time, the seller will send you an automated email stating when the item was shipped with an included tracking number.
Overall, yes I definitely say yes that it is safe but like I said above, always do the homework before bidding and confirm the seller is legit by checking their feedback and also contacting them beforehand if you wish. There are millions of people who use it and being that Ebay has done some more things over the years that protect the buyer and seller more such as their protection programs, it has made it even safer.
