Something I did Black Friday weekend, available again:
Omnitech 12-sheet shredder: $59.99 2 Staples photo papers: $29.98 filler.. I found something for : $0.50 Total: $90.47 Use 25% off any shredder mobile app coupon, -$15.00. Use $10 off $75 mobile app coupon (need the filler to get over $75 after the 25% coupon). YMMV on using two mobile app coupons in the same transaction, I've never had a problem.
$90.47 - $15 - $10 (+tax) = 65.47. Rebates of $35 on the shredder, $29.98 on the photo paper = 64.98. Basically pay only filler + tax, or if you pay with rewards, no tax.
Of course, if you don't need the shredder and can use the $5 off $25 on Sunday, you can just do two photo papers and a $5 off $25 and profit a little instead of "just" free.
