I've picked up a lot of business shipping cookies, but have to say the cost of shipping materials (bubble wrap, peanuts, etc.) is killing me! Sam's selection is extremely limited, and the prices at Office Depot and Office Max about gave me a heart attack.

Any ideas on where to get a good price on shipping materials?

The best thing to do would be searching google for shipping supplies. A couple of sites like ULINE should come up that sells the things you are looking for.

Have you built the cost of shipping into your overall price?
