I like how easy this integration was once we had someone from PromoFulfill handle it in getting everything configured correctly since they have done similar integrations between other companies as well! There wasn't much at all wrong about our experience however there were things where maybe more thoroughness could be shown such as what happens if something fails or goes awry during an order process etc.. but overall great service so far!! Highly recommend them - very good support staff who know their stuff when talking logistics/fulfilments.
