Costco currently has 15% back with a Costco Cash card if you pay for select Samsung items with your Costco Visa - https://www.costco.com/samsung-ci...?langId=-1
There is also a SamsungPay promo which can be stacked where you upload your receipt(in the SamsungPay promotions tab on your Samsungpay enabled phone) and get 61600 points(worth $300ish).
The 65" QN65Q7CDMFXZA TV from Costco should stack with both offers-
If you value the Costco GC as cash and the visa GC as cash, total will be -
$2879.99 - $300(samsungpay) - $432(15%) = $2148 + whatever tax you pay.
You also get a $50 Google play GC with the TV as well as free 3 year Squaretrade Warranty(don't forget the Costco Visa offers an additional 2 years for a total of 5) if you add that to cart.
Not sure if this is a good deal but I figured I would post it anyway since its the best price for this TV at the moment if anyone is looking for it.
Costo deal ends 9/9 and the SamsungPay promo ends 9/30.
-It looks like Amazon is offering the 15% back as well with their store card except it seems to be straight cash back rather than a Costco Cash card but you don't get the $50 google play & extra warranty.
