I'm selling a microwave on Amazon Marketplace and have a buyer that wants to pay/collect by EMS - driver gives me an envelope with money in and I give him a box with the microwave in it.

The whole thing makes me suspicious as I'm prepared to deliver it locally.

Buyer now wants my name, address and email address to arrange EMS and I'm concerned about the info being used to possible open a credit card in my name or something else nefarious.

Am I being paranoid or rightly suspicious?
