CVS never allows one discount to be combined with another discount until today. While shopping online, a box popped up giving me $10 off $40 + Free S/H on top of any other discounts being advertised on site. Right now they are running 25% off on regularly priced items. You will need an ExtraCare card, I think. So here's how to get both discounts:
1) Fill your shopping card with regularly priced items( not on sale) worth $55 or more
2) Go to check out and enter coupon code SAVE25 and click apply.
3) Then enter coupon code EXTRA10 and click apply. This code also gives free S/H
4) Enter ExtraCare card #-not sure if it's mandatory to have an ExtraCare card for the discounts to work, but it didn't matter to me because I have one.
Not sure when these codes expire, but both worked for me today and I saved $25
