Gatsby Customs review for Essential Upsell & Cross Sell

I tried a number of upsell/cross sell aps and non did what I wanted them to do in a clean, easy manner. Until now! This ap has a simple interface for setting up my cross selling addons and the support team was very responsive and implemented custom changes for me in less than 2 hours. So far, so good! I plan to check out and hopefully incorporate their other features.
