Aren't you pretty well limited to what the seller accepts? Paypalsucks.com lists alternatives, but I haven't heard from people who have practical experience with them.
Where do you buy coins that you pay with Paypal? Why do you want to use a different company? I'm not saying that Paypal is the only option just wondering what your reasons are. I've primarily used Paypal when I've bought items from Ebay but that is not too often anymore. I usually use a credit card or debit card when I buy my coins but I buy them from reputable sources such as the US Mint or BBB certified and/or ANA listed dealers.
I have money in paypal in USD AND EUR bill but I have no money in GBP bill. I have also bill with Sheqls because I am from Israel. I need the Dollars and the EURO to buy coins that I buy in ebay with USD or EUR and ib this case I have no comissin for exchange money from DOLLAR TO DOLLAR OR FROM EURO TO EURO. But if I pay GBP paypal make money with the exchange from USD to GBP--Now you understand the problem? I do not care if paypal will take the money from my crdit card with Sheqels, and the anount of Dollar will not decrees (more less Dollars in my bill). I ask paypal to not to use the USD dollar bill but I did not get repley yet. Thank you very much.
