I received an envelope from Walgreens in the mail this past week with a check for $25 in it. Well, I'm sure you know where things like this usually go in our house - to the shredder! But it turns out it was just another form of a transfer your prescription and get $25 to spend at Walgreens.
I wasn't sure if they would take it, but it turned out to be very easy to use. I transferred my prescription and gave them the check when I picked it up. When it was time to pay they put the check through their little machine and it printed a verification code on it. After that I was able to do my shopping and take the verified check to the front register and use it to pay for my groceries. Sweet!
