Rebuy Personalization Engine

Best upsell/cross sell app I have used. I've had trouble finding lightweight and properly built upsell apps to use. ReBuy has built a very clean solution that is way more customizable than I expected. We're able to modify the look of each component and the functionality. Additionally, their support team is great. They are very helpful and know more than cookie cutter responses --- they actually get their hands dirty and help you integrate into their tool. I'm grateful that someone has built this solution correctly, finally.
