HelloBoo review for AIOD Automatic Discount & Gift

I've been searching everywhere for a Shopify app that lets me offer free gifts based on cart value, but also allows customers to choose their own gift — not just auto-added ones. This app nailed it. I was able to set up a condition where customers spending $25 to $49.99 can pick anything from a $5.90 collection, and $5.90 is automatically deducted at checkout. Even better, if they choose something more premium (e.g. $7.90), they just pay the difference — super flexible and customer-friendly! Most apps only support strict free gift rules or force a specific item into the cart. I wanted more freedom for my customers, and this app made it possible. Super impressed! The only thing is user have to manually add the product into their cart, only after hitting the cart condition, then discount (-$5.90) will be implemented. Still looking for an app that will do that, but for now, out of 10-20 free/paid apps I'm searching, AIOD does the deed! Highly recommended if you're looking to create tiered free gift promos with optional top-ups and collection-based gift choices. Also instant customer service support! Thank you!
