1) create a money request and send it to the paypal you want to receive money from (do not under any circumstances just go "kk, here is my paypal, please send me XXX" - you will get scammed for "item not received".
2) under the details of the money receipt, place in the title and description "digital delivery of an intangible world of warcraft item - by accepting, buyer waives paypal buyer protection policy"
3) get the buyer to now send you an email from his verified (if its a normal account, do NOT deal with him and refund the money) stating
"i (insert name) of (insert address / phone number) hereby authorize the payment tendered of value (insert) to (your paypal) on (insert date) for digital delivery of an intangible world of warcraft item - by accepting, i waives the paypal buyer protection policy" attached is my IP address (tell him to copy and paste it from here http://whatismyipaddress.com/).
digitally signed (insert buyer name)
4) after you have verified the email address get him to tender you the money via the money receipt.
if the name or address or landline in the paypal money details does NOT match the ones he gave you, refund the money and request a western union if he wants to deal. do NOT accept echecks.
5) once you have the money, instantly move it to your bank account (it will be put on hold for 2-3 days) - even if he was to recall it, paypal would just put your account into negative and you hold the money smile
