Gains in Bulk review for HS Slide Cart Drawer Upsell

THIS APP IS AMAZING!!! My team and I have searched for such a long time to find an app like this. I can promise you that there is not another app out there as affordable and intuitive as this one. All other solutions for a cart drawer AND gift w/purchase are either non-existent or require a ton of customer work (expensive). TLDR: Amazing app
