I am trying to create a google extension that combines carts from different online shopping websites so you can easily pay for all your online shopping in one click. This will be especially useful with Christmas nearing, when people buy Christmas presents in bulk. This extension will save time because you won't need to enter you billing information every time on every tab. The extension will save you information, so you will need to create an account. I have made a design on what the extension will look like (attached screenshots). It is open for some of your own design eg. what you put in settings, the look and fonts if you choose. I would also like $5 from every purchase to come to me, so make that happen.
You need to create an extension. All buttons need to be able to be pushed and it needs to be able to be connected to every online shopping website. So when you push connect all of the items in the cart on the website will transfer to the cart in the extension and you need to be able to do this from multiple tabs, to make large purchases. Any questions feel free message
