ah man, we have tolls! There are 4 of them in my immediate area. If you hit all of them to and from, they are $12.60 and the dang state just approved a DOUBLING of tolls so they're going to be $25.60 going forward. Ugh. I'm signing up for an EZ pass just for shopping. Oh, and I should add the $12.80 is just for passenger, two axle vehicles such as sedan cars and pickup trucks. If you drive an RV or a 5th wheel, have a hitch attached, drive a rig, have a work truck, drive anything with 3 axles or more etc. etc. the fees just climb!!! The oversized trucks pay a whopping $12 before the frackin' fee doubles soon! I cannot imagine.
So you are being paid $4 for a MF shop and picking up another $12-16 for toll costs for the day? That significantly increases their costs for the shops you do. I understand why they have flagged your account for review. I'm amazed that they are continuing to pay tolls for all their shoppers.
I don't "charge" them for any tolls I wouldn't have to pass through for their shops. I'm always careful on that! If it only requires me to pass through $8 in tolls and I use another $4, I'll only put the $8 on my shop. Perhaps that's another reason too because the tolls are not "consistent" in that it's not the same tolls all the time because I do other shops, take other roads, double back, and so forth but I just flag the ones I use for their shops.
