For anyone struggling here is what I did:

Go to this link: http://www.amazon.com/gp/shopwithpoints/marketing.html?pr=swpchaseur

Linked my UR card which was already on Amazon so I just clicked accept

Found an item shipped and sold through Amazon (in this case I picked these baby wipes)

Added it to my cart, proceeded to check out, use the Chase card as the form of payment

Applied $0.01 from my rewards equaling 1 UR point

Applied the promo code SWP15CH15D and then clicked continue once I saw the $15 balance

Applied subscribe and save for another 5% off of the principal value (going to cancel the subscription later).
