set sales

I encounter the set sales headache, because I really can not organize a complete statement expressed in its true meaning, translation can be translated, but after translation mean I do not understand, but no one toldI mean, in the end what it meant, in my own translation of the results, I understood as a centralized sales, but the focus on sales translated into English words, because his English is not very good, so I do notbet its Chinese meaning what is this problem only to keep to be later inspection.
