I sold something on ebay, they wanted to pay buy credit card, I had to refuse as I only have the personnal account, it was not on ebay to take credit card payments, but been told you can have two paypal accounts, one prem, one personnal, so do you use the same email, and how does it work with ebay, so you have 2 accounts
IF they want it, they should be willing to pay you in a manner you accept. i assume your selling page detailed the methods of payment you accept. if they are trying to make you accept a method you did not list, that is their problem.
If you said Pay Pal only, amd they want to pay by Credit card. Just say "no, the sale said pay pal only, pay up, with Pay Pal, or i will sell it to someone else"
And if they offered well over the odds, perhaps it is a scam to seperate you from you stuff, without paying for it.
If i bought somthing, i could pay with pay pal, personal cheque (i wait while it clears), building Society Cheque (ditto), Credit card (if you took it), Postal Order, or cash on the doorstep. It would be up to you, the seller to tell me how to pay. Not up to me to tell you what method to accept.
