Generous and greatly supported

This plugin is probably the most generous upsell plugin in the WordPress repository -and I’ve tried most of them in the last days-. The free version includes interesting features which other plugins offer only in their paid version (such as “after x days expiration” in the next order coupon campaign, or several conditions).

The support is also great. They solved my question with illustrative images to make sure I wouldn’t miss the solution. Thank you, UpsellWP team!
