BOGOS: Free Gift Bundle Upsell

This app has by far the best customer service of any that ive tried before.
The developers, Brian specifically, was extremely helpful getting the app(which works perfectly) setup, I had an issue with my theme, not the app, that he resolved. Anne was also very helpful and quick to reply and made sure everything was in order.
Edit: Back to add some more info, I have used this app to do a free gift over xx amount, and it works great, if the cart value gets reduced, and the gift automatically removes itself. It can also do multiple offers at once, where the customer can get a gift for over 50 or a different gift for over 100, or it can be set to give both gifts if they go over 100. It can also give gifts to first time customers, and only show that offer to first time customers.
