How to make more money with upsells

A really long time ago. was selling a course on GumRoad. I had multiple different digital products and I had a core one and kind of like supplemental ones. And then they introduced this thing where you CAN package multiple products together. So what I did is on the on the main one, I set them as upsells. And what happened was instantaneous increase. It was somewhere around like 30 to 40% take rate on the upsell. So you just made an astronomical amount of more money.

If you want to make more sales, have an upsell to increase revenue
