It's easy enough that I can teach it without any help from anyone else at my store! You could definitely do more with this tool - like more features in general (even if you don't want them).
We've been using future margin since August of last year when we implemented our new retail program into an existing site. The benefits have already started showing up right away but there are still some things i'd love to see done better as well :) I think their support team has helped us get through most issues so far too!! If u're looking for something simple yet powerful then go ahead & give futuremargin a try. They really know how they should build out such products which helps me trust what they say even though its not always perfect ;) we dont run many promotions or anything crazy here just normal stuff, forecasting customer behavior and helping keep shelves full while.
