I got mine in the mail not too long ago. It's a nice gesture but I would've preferred they ask if we want one. It's discounts of full prescription prices and the only scripts I get are either cheap co-pays or covered in full by no fault. They could've saved money by not sending me a set. I'm sure many others can't benefit from them either. That adds up.
Of course, now that I've written that, I'll have a script that won't be covered and I don't have a clue where I've put the cards. I wish I knew someone I could give them to. It'd be nice for someone to get some use out of them.
