Dude just offered me $260 for my $200 NFL shop gift certificate if I agree to cash a $1500 check and send him the difference. I told him I'd do it if he agreed to give me $650 for it and he "reluctantly" agreed...
I just replied back saying that since tomorrow is a bank holiday, I could only hold the gift certificate for him if he agreed to give me all $1500 and send me a check for $2000 instead and I'd send him back the remaining $500.
