Once you sit down in one of the stalls, an ad wrapping the back of the door invites you to download the Amazon App and displays the barcodes for coupons for several bathroom-appropriate items. Use the app to scan the barcodes and place your order.

In that spirit, Amazon and Proctor & Gamble have partnered up to launch "Stall Malls" inside public toilets.

There's no reason productivity should stop at the bathroom door.

So while you finish using the bathroom, you'll also be scratching an item off your to-do list.

To encourage users to take the plunge, the coupons are on the high side for what the brands offer.

The coupons include $2 off Charmin Mega Rolls, $7 off Crest 3D Whitestrips and 50 cents off Febreze.



The ads will be installed in select cities through the end of the year.

You can find them in New York at Paramus Park, Staten Island, Willowbrook, and Woodbridge Malls, in Los Angeles, at the Glendale Galleria, in Philadelphia at the Christiana and Neshaminy malls, and in Seattle at the Alderwod, Bellis Fair and Westlake malls.
