Guess I'll share my experience. I was able to enter the raffle and received the text w/o any hassle. Went for the Taupe, entered my CC info and everything. Got the submission message and waited.
Unfortunately, I didn't receive any invoice via text or email. it seems the issue was going for the Taupe instead of the Desert Moss, which I'm fine with because I'm not a fan of the Desert Moss.
Hopefully in the future, Union opts for a more sensible approach to selling their product. Raffles are always a crapshoot.
