I don't use voiceshopping or the scanner wand thing. I feel the need to check pricing before I make a reorder as often the seller I ordered from last time isn't the lowest price this time and I don't trust Alexa to price shop for me (or correctly).
According to Business Insiders electronic shopping tools analyzer, only 193 people tried to use Alexa to shop from Amazon with only 91 being successful all the way to check out and only 57 of those repeated that method of shopping with 41 of those ordering the exact same item.
I despise the whole idea, and I have no idea why anyone would actually pay to have a device spying on them in their home. And I generally love technology and gadgets.
