Terrible. The app missed 15% of the orders. We are in cleanup hell.
We attempted to use the Gift Box app for a Fathers Day GWP promo. The app was easy to install and configure, but unfortunately that is where it ended. We tested and everything seemed fine but as soon as our site started getting busy the app began to miss orders.
On the plus side, Tom was quick to provide support but our problem was not resolved and he suggested that we test other GWP apps.
