EG Auto Add to Cart Free Gift

We are using the App for more than 6 months now, automatically adding free perfume samples to specific orders. It works great! Today, we have had an issue with the samples not appearing in the cart, and we contacted the support. Nathan provided us with a quick (less than 1 hour!!) and efficient answer (actually, it was on our side, we did something wrong with the publishing parameter of the samples product). Great product + great support = happy merchant! ;)
