Its just a registration,,basically the same as ebay but they require you to either put a credit card number or link to a bank account !! Do not put your credit card numbers in or link to your main bank account !! I just went and bought a pre paid MasterCard for $25. and used that !! Or you can set up a separate account at your bank for online sales !! That prevents any problems if a complaint is filed should that happen !! Keep everything you do online separate from your personal accounts !! If you set up a separate account for online sales,, you can go into paypal and simply transfer clear funds to your personal account !!
