This idea comes from user Jediross who posted it in the comments on the Amazon Sharpie Pens Thread I suggested posting it as a thread but he hasn't got round to it but I've used it so much since and found it so useful I wanted to share. But it isn't my idea it's Mr Jedi!
In a nutshell put an add on item in your basket. Then use the voice commands on Alexa to make the order. It does not add on the P&P and you do not have to spend the £20 minimum.
With Christmas coming its great for stocking fillers.
