Verdict on XB:

XB is a simple, free, and Built for Shopify-certified app for stores that just want BOGO and free gift promotions without complexity.

Best for merchants who want a lightweight promotion tool rather than a full bundle builder.

Verdict on ABU

ABU AI is a bilingual Spanish/English upsell tool targeting Latin American markets. The AI-powered recommendations are a good concept, but with only 1 review it is unproven. The free plan is extremely limited at 1 order/month. Best for Spanish-speaking store owners who want native-language support.
