Amazon is encouraging shoppers to do something retailers hate on Black Friday (AMZN)

Amazon has a new plan to draw customers to its site this Black Friday.

In addition to its usual slew of discounts during Black Friday and the days immediately following and before, Amazon is offering a different kind of discount.

This year, it’s offering a $5 coupon off certain sale items just for using certain features on the Amazon app. Customers need only fire up the camera search or AR View features to nab the discount.

To use camera search, customers have two options: either search by taking a picture of an item to search it on Amazon, or just take a picture of the barcode to look it up on its website. Search results will be instantly available, and if Amazon sells it customers can choose to purchase instantly.

The discount tied to camera search is especially notable, as it seems to explicitly encourage something many physical retailers fear: showrooming. That’s when customers come into a store to check out an item, and then leave to purchase it online.

Amazon’s $5 discount, plus a potentially cheaper Black Friday price than the one the store is offering, could be just enough to tip the decision to purchase into Amazon’s favor.

Especially when adding in the fact that Amazon has removed its free shipping minimum for all holiday purchases to the calculus.

Amazon is also offering other options to get the $5 discount, AR View. This uses the camera to render the item — usually a large one, like a piece of furniture — and see what it would look like actually in a shopper’s physical space.

Amazon has been offering Black Friday deals since November 16. On Saturday, its Cyber Monday deals will begin and last through the week.
