Kaching Bundles App & Upsells

I had a tricky issue with my "Buy 3 Get 1 Free" promotion where the free gift wasn't being added to some orders. Dovydas from Kaching support was incredibly helpful — he patiently investigated the problem, explained why it was happening, and guided me through the best solution using Kaching Cart. He even offered to set it up for me if I needed help. Really appreciate the excellent support! Highly recommend this app and Dovydas to anyone using Shopify. Thank you!
