Upsell Kit: BOGO, Bundle & 30+

This app has been excellent for me, and the support has been fantastic too.
They even added a feature specifically for the issue I was having!!

The app is useful for showing the stats for how many items have been "upsold", so great to see if it was worth implementing, and also for management purposes too.

I will be looking at using their other tooling soon to complement my website further.
