Query: Great unless it's OLD

This is a great vitamin. I have used it in the lesser 500 mg dose.I was glad to see the higher dosage, but really disappointed when I saw the attached coupon which expired in 2010. I ordered these 5/12. The vitamins expire 12/2012. Gosh, have these been sitting around for 2 years?! Now what about the potency? Sad. I'll stick to the 500mg tablets. I have to take more tablets, but they're fresher. I'm out of money and time because it wouldn't be cost effective to return them.
