I have never had one bit of trouble in this country with paypal, set up to draw on my bank account, and I actually prefer to deal with a vendor who uses it. I gave up using credit cards a couple of years ago because of their exhorbitant charges if you didn't settle up straight away, but do use a debit card.
Having dealt a lot with international purchases, especially the US, here are a couple of facts you should consider.
Even though US suppliers state that they accept certain credit cards, most won't touch you with a bargepole if the card wasn't issued by an American bank actually based in the US. You really do have to read the fine print.
Paypal to the US is also a bit of a gamble. They will say that they accept it, but when you come to pay, it usually isn't as straight forwards as you think.
You first have to order your bits, then contact them by email, and they will then issue a payment slip which you then pay with your paypal account. It seems like a lot of them can't do it automatically, as they do in this and other European countries.
You have to go thru all the fine print on their website to even find out if they will export to the UK. It seems that the US government is paranoid about technology being shipped outside of the US, and restrict the suppliers where they can ship to, or the suppliers won't ship outside of the US because of possible comebacks by the government.
This is information that was supplied to me by an American supplier who bent over backwards to help me obtain what I wanted, but ended up not being able to supply because his hands were tied.
I eventually got all the pieces for my twenty year old mo'sickle by going the long way around with Paypal. By the time I had swapped all the info, because of the time zone differences, it took about two days to complete the transaction, then another four weeks before the impossible USPS got the bits to me (to send by courier, the charges would have been more than the cost of the items). I had a $40+ order that fitted into a medium sized Jiffy bag cost $69 in courier postage (and no other postal options were available).
