I'd be okay if they redid the thing with an eInk display. You press once to activate the device and retrieves the current price, and you have to press it once more to confirm the purchase.

To be honest I'd still buy one just to tinker with it and see how far I can customize it to do something else, but Amazon wouldn't benefit from it so they'd have an incentive to block people from doing so.

I think the single button with no screen is actually kind of a nice idea. you buy a few, put them in strategic places (sponge button by the sink, paper towel button by the paper towels, etc), and just hit the button when you're running low on something.

the main deal breaker with the current setup is that the price might shoot up unexpectedly, but this could be fixed with the ability to set a price limit when you configure the device (eg, don't spend more than $5 on a pack of paper towels).

I believe they offer an "IoT" version for this use case

Interesting, I'll have to search. I was already planning to build my own with an ESP8266.
