Upsell Kit: BOGO, Bundle & 30+

This is an awesome upsell app and support is on top of it! I had a small issue of my custom theme overriding this apps' checkboxes and positioning, after trying to solve the issue myself for 2 days I decided to finally reach out to the support team. I sent them 1 message with my 2 issues and a link to the page its on, and they responded saying why its happening and they can fix it. Just a few minutes later both issues were fixed. Highly recommend.
