How about 36 boxes of 85 sheet Kleenex, $28.17 shipped when you clip the $5 coupon on the page and check out with subscribe & save? That’s only $.78 per box, shipped to your door — even less if you are on the 15-20% off subscribe & save tier!
Prices on Amazon often change quickly. You need to be logged in to see and clip coupons, which are limit one per account and will come off just the first shipment. You can cancel subscribe & save or skip a shipment at any time. You get 5% off and free shipping with subscribe & save, which increases to 15% off if you have five subscriptions on the same day/month, or 20% off if you have five + Amazon Mom with Prime — in which case your price will be even lower than shown above!
