First time posting a deal.
If you are a first time Google Checkout user (or create a new account) with an eligible AMEX cash back deal for $20 off purchases of $60+ on Google Express this will work.
Go to Google Express and add the controller to your cart here which is from Target:
My total came to 74.89 with tax for the controller. After I applied the 20% off promo for first time Google Express buyers SUMMERFUN
my order went down to 60.89 which qualifies for the AMEX cash back offer. After your purchase with your linked AMEX card on Google Express you will receive the $20 cash back from AMEX bringing the cost of the controller down to 40.89. Your deal will vary depending on the tax in your area.
Save 20% on your first order, up to $20, with code SUMMERFUN
