Cost of coral calcium

Hey there
so what's the cost of this coral calcium. I'm not working anymore so money is a issue, but I'd really like to try it. is it okay to use with meds?? is it cheaper through a web site or should I go to a health store...
Love
Lisa

I just bought some a few days ago at Wal-Mart for about 6.00 for 60 capsules. I can't attest to the effectiveness of it yet since I just started it; but, a lady that was standing next to me told me that it was "good stuff". Her husband has lupus and takes it and does well. She said he used to take the more expensive kind and they were glad to find it for less. That's about all I know....good luck
