Moo! The Musings of a Plaid Cow

On a Consumerist post, downwithmonstercable replies:

I get offers in the mail all the time to use “convenience checks” for my cards that give me a 4.99% rate or something. I don’t get it though. How is writing a check more convenient than a card?

That sounds kinda like a Jack Handey deep thought. Except way lamer.

I can’t figure out if he’s a clueless idiot or a clever troll. I’m guessing clever troll. I mean, if you don’t know why you would use the convenience checks that came in the mail, how about you read the advertisement that came with them?
