A hot thread for GTX 2080 has been posted. This is probably quite overlapped, but I see that many people having an issue applying the coupon.
Here I add another 15% coupon code and summary the process for applying these coupons successfully. I collected this information from the comments in the previous thread.
15% OFF coupon: 79553
30% OFF coupon: 83856
100 OFF 500: 89277
The first two can only be used by Staples Plus member. If you are not a Plus member, you can simply search "Staples Plus" on staples website and click join now. Be sure to have your GTX added to your cart already. Then you will automatically be directed to your cart and you are now able to apply the 15% OFF and 30% OFF coupons.
You can only apply two coupons for one order.
Thus, for GTX 2080, you should use 83856 and 89277.
And for GTX 2080 ti, you should use 79553 and 83856.
Finally, you will get GTX 2080 ti at around $707, the total price would plus $50 for Plus membership and tax.
You can cancel Plus membership in 30 days with full amount return.
