For those of you who haven't had the pleasure.

A check comes in the mail for some small amount.
It's a good check, made out to you.
This one is from YP.COM INTERNET YELLOW PAGES

It's tempting to endorse it and add it to the deposit.

Don't Do it !! :eek

Read the fine print over the endorsement.
"I agree to pay $27.50 per month in advance...and authorize ...direct debit"

Bad news. toss it
