I like that you can set it up to be able for your customers (and yourself) what they get when purchasing from one of their favorite stores or websites! The only thing is if this doesn't work with certain retailers/websites then there's no way around having someone manually enter all those codes into our system which takes time out away form other tasks we need done in real-time instead - so maybe look at some alternatives? It definitely helps us keep track better than any spreadsheet could ever do alone!!
