What is the best way to accept payment from a private buyer that protects us both?

[Mhill1710]

I'm trying to buy a product from a private seller, and paypal seems to be the best option, however, the seller wants a bit more security, would him requesting payment be the best option or can he generate an invoive without cost that protects him as much as me?

you two should review both buyer and seller protection,some items are not protected,
