Since Thighber Monday only comes around once a year, we highly recommend grabbing that free gift instead of using another promo code, because we can only honor one code/promo/gift per order. You can still use a promo or discount code if you'd like, but that will mean you won't be getting the free gift with that order.
If you are using a military discount code, check out our article on that here. Military discounts are the only discount codes we can honor retroactively on Thighber Monday.
