If you don't have a CVS Extra Care card you need to go sign up for one. Right. Now. Here's a link to the Black Friday Deals that actually start on Thanksgiving Day, complete with links to printable coupons that will actually let you make money. Seriously. And yes, I will be there on Thanksgiving Day because it will be way less busy and we never go home that early in the morning.
If you don't have a card yet or any ECB's, you can do multiple transactions. Just buy a thing or two, then use those bucks toward the next transaction. The cashiers are always really nice about doing this.
