Not this specifically, but with a totally electronic system and no point of sale to anchor there is large opportunity to easily and programatically have dynamic pricing at the known individual level. Supply, time of day, whatever can be instantly baked into a pricing system.
And why not? No humans needed to change pricing. Plus i would think you could scan to get "your" price. Prime member $x. Etc..
It's hard to do that in a physical store since everyone can see the same price display. I doubt many people would be happy in a store where they need to look up every single price on their mobile device.
Kohl's seems to be doing pretty well with that system. They print a high price on the tags, then discount it by rack, and mail out 30% off coupons with short expiration dates to some of their rewards card holders every month.

I hope i did not imply this was happening now..
