Remember, wholesalers don't do squat to move your product. That's your job. Most often they are close to the mark. These people have a good track record on how to price books. Don't be afraid to question the reports you get.
Many distributors have terrible computer systems and poor data entry accuracy.
Make sure you reconcile the number of books you have sent against those that have sold against those still in inventory. Don't screw your distributor. If a store places an order with you, do the right thing and send it on to the distributor. If they hear that you filled it yourself they will be pissed and the last thing you need is a pissed off distributor. When you get one or two books returned by Ingram, call your rep and tell them how upset you are.
