Add 3 to the cart, in any combination.
So, add 3 of one toothpaste, or one of 3 kinds of toothpaste.
Log-in to a Walgreens account (or create an account).
View the cart.
Under one of the toothpaste is red "Coupon Available" text.
Click "Get Coupon" next to it.
At the bottom of the coupon list, click the "$7.00 Off Three Crest and/or Oral-B" coupon.
Return to the cart to see a $7 off discount.
Three of $2.99 toothpaste with a $7 discount comes to $2 plus tax.
Proceed to Checkout.
Choose in-store pickup to avoid a shipping fee.
Walgreens only has curbside pickup for toothpaste at select locations, so you may need to walk into the store to pickup your order at the register.
This is different than their prescription drive-through, where many locations allow picking up prescriptions and some wellness products at the pharmacy drive-through.
