Joins typically take place between a primary key on one table and a corresponding foreign key on the other table. The syntax of your joins seems fine so I can only suspect the two things I said above. For instance, if Vendor.PID is intended to be unique and you think of it as the primary key but it hasn't actually been defined that way in the table, it's very possible that this is causing your duplicate rows.
