Amazon Dash is a pretty sillyway to reorder various products from Amazon.

Papathanasious version gives you a lot more control over what you order and how much you pay.

Essentially, you hook a Pi up to a scanner and scan items you want to order.

It works with any product and you might say no to an order if its priced too high.

Basically, its an Amazon Dash thats actually useful.
