I would consider this a happy accident. Perhaps this is an opportunity to reevaluate how you value your time and calculate your own expenses. This is a business. The MSC would not offer to pay you more than they felt the job was worth.
CEASE - You may be the only one who is participating in this thread who thinks that $75 (total) is the correct compensation for driving over 1000 miles and spending 20 hours doing so. Even $750 is a bargain. That is why they are paying you that fee.
Shopping Southeast Pennsylvania, Delaware above the canal, and southwestern NJ since 2008
I enjoyed the discussion. I ended up completing 7 of the shops over 3 days (mini-routes; picked up a few "filler shops" -- gas stations and ff), driving 1300 miles.. Because of the mileage, all "tax sheltered", so it's cash flow, baby, cash flow!!!
