Glory Cloud USA review for Wizio: Bundle Free Gift Upsell

I have tried 5 different cart free gift/free shipping promotions and there have always been errors or issues with them that made it to difficult to use on our store. This is the first one that has been usable. It isn't perfect as I guess Shopify's cart and checkout coding makes some things unchangeable, but it's been working well for us overall and support was helpful with minor issues we've had.
