Hopefully, you have a CVS Extra Care Card and have registered it online. Then, go HERE and enter your email address. You will then be able to print a coupon for "Buy 2, Get 1 Free". Beginning Sunday, this coupon will allow you to buy 4 for the price of 1. They will be on sale for "Buy 1, Get 1 Free".
Here's how it works.Take 4 to the counter.
They will ring up:
minus 9.99 (coupon)=9.99
So you will get 4 for 9.99. Please remember that you have to pay tax on all 4.
