Just got back from Walgreens. They have Walgreens Calcium+Minerals 500mg on sale for $10.99 for 400 tablets. They are the same as Caltrate Plus, except the calcium is 500mg instead of 600mg. That figures out tobe 3 cents ea. as opposed to Caltrate Plus at $6.99 for 60 tablets or 12 cents each [with taxes]. Hope they work as well. I can supplement them with Tums or a fourth one if I need it. Actually with the JAF, the 500's should be more than enough.
