My CVS will no longer let me stack the CVS $/$ coupons. They did let me use more than 1, but they added the total purchase $210, and allowed me the following;

$15/75, $15/75, $10/$50 and $2/10, if you add up the totals $75, $75, $50 and $10 it comes to $210. Bummer. They said it was their managers new policy due to a memo from corprate office.

Think I'll try a different CVS and find out what happens.
