There is no way to do this on our site with normal payment options UNLESS you use an Obsessed Garage Gift Card. Use your first method of payment (Visa Gift Card, Debit Card, etc.) to purchase a VIRTUAL OG GIFT CARD. Then fill up your cart as normal and checkout with that gift card code FIRST, then use your standard method of payment (credit card, PayPal, etc.) last. You can do this with as many Obsessed Garage Gift Cards as you need, just always use them first.
