I absolutely love OrderBump, we use custom rules to enable our customers upgrade product in checkout and post sale. On average we manage to upgrade 10% of customers!
The app works great out of the box, and support is excellent in helping you get setup and make any changes. Since installing we've seen good engagement with upsell offers and has ultimately increased AOV
Superbump is epic for post purchase upsell offers. We've driven hundreds of conversions since launching a few weeks ago and are seeing double digit increases in AOV on some days from the month prior (Without SuperBump installed). Highly recommend the app to anyone seeking to raise AOV on their customers. The SuperBump support team is also top notch and responds within 24 hours. Highly recommend!
