Buying something sight unseen has always been risky regardless of where you see it advertised or the method of payment.
I have a PayPal account and it is tied to the my Gmail address, but it is the same address I used for my day to day correspondence. Actually, my preferred method of payment is still a good ol' Postal Money Order.
Oh, I am also a member of three blue lodges in Missouri and Past Master of two of them. Maybe that makes me more trustworthy!
