Can't use coupons in the Benefits page/xbox console

[Kain119]

So I am posting this, knowing that It may make me look stupid, but I don't really mind. This is in regards to the coupon system that is in the benefits tab of RDR2 online. I have a large collection of coupons saved up mostly for free items, such as a hat, two for coats, a few Metal changes on guns, and one free repeater gun. I have no idea what so ever how to use these coupons as there is and has never been any prompt on any item to apply a coupon, whether I use them from the benefits tab or inside the shop directly. I mean I guess I don't really care if I get the items, but it would be nice as they area a part of the Bounty Pass I unlocked. The only thing I can guess is that the coupons are limited to certain items, and I must already own the items they apply too so I cant use the coupons? I also have ones for discounts on or free horses and I can't apply those either. It honestly doesn't make any real sense to me, and I haven't seen any videos or much of others having this issue. Any advice, or if we can get this seen by DEVs so they cant maybe take a look at the system and think about changing it so it works better would be wonderful.
