I will be making a delivery to this warehouse and have been told I will have to pay a lumper to unload the truck. Will the lumper service accept a ComCheck for payment. I have had other services refuse ComChecks in the past.

Yes

They accept Comcheck.

Yes you can use ComCheck

I think they will although i am a direct bill

They accept payment from everything, but they will give you a piece of paper instead of using a Comcheck. If you have the Comdata MasterCard, they will accept that, too.
