Okay, so the simple story is that CVS is currently offering coupon code SAVE30 for an additional 30% off regular prices and free shipping on every order.
The slightly-more-complex story is that precious little is available at these so-called “regular” prices, and a lot of the stuff that is regularly-priced is more expensive than where you can find it elsewhere. So why do you care? You care for one or both of the following reasons:
1) There are some speciality items offered at regular price which hardly ever go on sale—think hypoallergenic baby formula, or blood pressure monitors, etc.—which are coupon-eligible,
2) There’s a slew of Buy 1, Get 1 Half Off deals plus Buy 1, Get 1 Free vitamin/supplement offerings on the site which will not take a further discount, true, but the coupon code will give you free shipping on some already great deals, and save you a trip to the store.
Definitely compare prices as you shop, but I did find a few things we always need, anyway (fish oil! chewy antacids!), that I was glad not to have to get to $50+ total to get free shipping.
