The best part about this service was that it allowed me as an individual seller with no inventory of my very low profit margin products (mostly electronics)to sell them through Amazon without having any warehouse or distribution center personnel involved at ALL! I could just put up listings for items which were already listed by other sellers but not yet shipped from China/India etc., then let these 'fulfillers' do what they have been paid handsomely NOT TO DO - i am sure there are many more companies out here who would agree wthme 100%. There's nothing really bad abtwarehouse services per se; however if you're looking into using one be prepared fo some major headaches down th path because most will want "their" way rather than yours when dealing directly witheverything else related tpampaigns suchas shipping logistics &cetera..
