Paypal worked for me but I only used it once. The way i could see it causing a problem is because you are redirected to paypal's site to login and choose method of payment, once that is done you are redirected back to the site you were on which could cause you to get the SPA page or lose your item so its best to just check out the regular way. Sites like FTL EB CHM store your card info if youre a member and all you have to do is enter the 3/4 digit number on the back of your card. NDC doesnt offer paypal i dont think anyway. FNL is a nightmare never redirect away from FNL just pay the regular way
