I sell books on eBay and use the template feature in Poco, not the scripts. This is my basic congratulations template (to a US winner):-
--------------------------------------------------------------------
Hello,
Congratulations, you are the highest bidder for the above titled item. American funds are fine with me, I have a U.S. account here. A money order will ensure immediate mailing while a check will cause a delay on the item for only a day or so. If there is good feedback I do not wait the whole 14 days for a check to clear. Either form of payment is fine with me. I also take Paypal.
Please send $ American, which includes surface postage, or $ for air mail. (Surface delivery between Canada and the U.S. can take between two to four weeks. On some very rare occasions it has taken close to six.).  I would appreciate a brief reply, then I know things are on a roll.
Thank you very much and here is my address:-
-------------------------------------------------------------------
I have several other ones to use for different circumstances, like international winners, someone within Canada, or an extra large book where I need the postal code, etc.
I find templates the perfect and quick way to go, I'm not very good with scripts. Hope this helps
Maureen.
