Nick left a great comment about checking your CVS account for a FREE $1 or $2 ECB, below is what Nick has to say:
Since CVS starts their ad week on Sundays it is a good idea to see what offers are in your account and strategize. Today I saw a new $1 ExtraCare coupon sitting there and I hadn’t done anything. What is up with all these mystery rewards ($1, $2…) which are popping up randomly?!!! Of course we’ll take ‘em. But do get in the habit of checking your account often. The $1 for me has a short fuse (expires end of this week) so use it or lose it.
