TERRIBLE CS I've bought the pre-order module for Magento 2. The support is not great at all. They answer quickly but never clarifying my questions. They want more money to implement a standard functionality. the items are never secured. One person may pre-order an item and when it's back in stock... anybody else could order it They say that this is a standard workflow(!!!!!).. with extra money they could develop this "weird" requirement... I don't know how other people deal with it, but the CS wasn't able to answer. Totally not satisfied. I had to open a claim through PayPal because they are not refunding me
