Credits are only a calculating unit of the information quantity which you have chosen from WIN databanks. 2 credits = 1 company information. For example, any WIN member can search 150 Chinese importers information every month, that means he or she has 300 credits. If you confirm to buy 2 items from Chinese Importers Databank, the balance of credits will be 296. At the beginning of every month, you can receive the credits automatically, and the balance will not be added to the next month. Credits alloted by WIN are free of charge.
