Just be careful!
I just had a terrible experience at Ebay -- not with Ebay, but some hacker at Ebay. Somehow, someone got into my Ebay account and started selling things out of it. We have never even signed up for a sellers account -- we just buy!

Anyway, someone was able to set up an account with them to sell (which requires financial information -- we assume they used the credit card attached to our PayPal account for that) and try to sell a laptop from the UK!!! It was going for $1,100 (I forget how many pounds that translated to) by the time I figured it out!
I would never have known until the auction was over if it hadn't been for the fact I couldn't get into my Yahoo! email account for several days. I thought it was a problem on their end -- but finally decided to send in for my password and they reset it. When I went into my account, most of my emails had been deleted. Then I went into all my other folders and found, under the Sent folder, a message sent from "me" to someone else regarding the laptop "I" had for sale. At first, I was ready to strangle my husband!!! until I looked closer at the item and realized I was now living in the UK!
Anyway, we've had to cancel credit cards, change many, many passwords and etc. just in case. It was a nightmare -- and took several days to straighten out.
It would have been much easier if Ebay had a phone number! It takes forever to email back and forth -- considering I kept thinking of more questions! Although, they were wonderful and hopefully everything is straightened out now. And I didn't even get any nasty emails from disappointed bidders, like I thought I might.
So, although we've had lots of success buying things at Ebay, I just wanted to share my story to make sure everyone keeps their eyes open regarding their accounts. Apparently, it is possible to get your account taken over quite easily. Make sure and check your account over every once in a while -- especially if you don't use it all that often!
