I ordered 2 sweaters for $30 and noticed there was a banner on the bottom of my cart that said $30 back in Rewards you can redeem on your next purchase when your order ships.
I was curious so I opened up a new page and added a .99 shoelace to my cart. Banner still appeared on the order confirmation page stating $30 in Rewards. With shipping being free this seems like an awesome deal if it all goes through with a .99 item.
This is what the banner said.
