Selling something online

[heissu]

I want to sell something of importance and value online. I have found a suitable buyer but he requires me to post the item.

Would I have to worry that he could somehow do a charge-back after doing a tilisiirto by lying that it was to the wrong account or something?
I have never bought anything online without some sort of guarantee and I know I won't get one here. I just don't want to wake up one morning and see the money gone.

Thanks

If the money is already on your bank account, he needs a court order to extract it involuntarily back from you.
