Rapi Bundles Builder & Upsells

We have tested various apps for bundles and have also used Rapi for some time. In itself, the app is good, despite the limited range of functions - after all, it's free. Nevertheless, we ultimately decided against it because there was a issue that bundles did not work at all (“Don't worry, it's just a sync problem”) that was not solved for several days. In addition, the support initially requested full access to the entire store, which was unacceptable for us. We don't run large stores and don't have a lot of staff, but we still (or perhaps because of this?) need them to work as smoothly as possible.

Unfortunately, does not tick all the boxes. Seems to be an issue when you have certain types of variations at different prices. It still provides the customer with the cheapest price even when that option is out of stock. Possibly resolvable but needing to reach support for basic features in first few days is a no for me. For the price have used other apps that seem better and provide upsell features. Serves as a good app but limited.
