Axe Checkbox Upsell Order Bump

I did loooots of research to find intuitive, easy applications to use for my upsells.
I can tell that Axe Upsell Checkbox was by far the easiest and quickest app to implement that I have found !

It has already great custom options / tools, without being overwhelming which I find is super rare for all these apps !

The support is also super super fast and efficient. They will absolutely help you until you find the right solution.

Thank you !!!
