Awesome that there is a military discount. I had trouble with my credit card info though. I entered the correct number several times with autofill, but the form kept saying it was incorrect and wouldn't let me proceed. I verified it was correct from my physical card. I don't know who manually enters their credit card info in 2023. The website needs to accept autofill info.
Unfortunately, after an order has been placed, a modification, in any way, for any reason, will result in the reversal and cancellation of your cash back. This was prominently displayed at the top of the “Details & Exclusions” shown with the offer you clicked. I'm sure you're frustrated by this, but please know that CouponCabin shares this feeling with you as we, too, will lose our commission for your order.
