I am at the payments section, my cart is all set, and I’m ready to purchase my M RTA addy. I received a new customer first purchase coupon code via my email, but nowhere within any steps through the checkout/payment process do I see a text box wherein I (in theory) would enter my coupon code. Please help me figure out how to apply my coupon, I’d like to place said order soon before supplies sell out, and I want this RTA badly:/
