We do some business with them and you are right about cheap.
Regarding freight, they only give out what their own trucks and drivers do not want to haul. Milk runs or 300 miles from the closest reload type of stuff...
Regarding payments, it all depends when you get your invoice and POD's in. If its after the 20th (I think. Its been so long, I forget which day) it goes to the end of the following month. If its before the 20th (??) they usually cut a cheque the next month around the 15th.
If you give them a load, they will solicit your client. No if's, and's, or but's. We no longer give them loads (Grins)...
