Need coupon to get the rebate the print out. It’s available on staples website https://www.staples.com/coupons
The math for single ream is $7.99 - $6.99 ER = $1
They are also running buy 2 get 1 free for these. The rebate limit is 4 per household but I’m not sure how it would work with the B2G1. Potentially $7.99x2 - $6.99x3 ER = $4.99MM YMMV
There is also expired last week’s coupon that takes $2.98 off on Sun/Mon. Not sure if the two coupons would stack. YMMV.
