Donm't understand the last sentence of Timberwoman's post, but--this is why Lifesaver incorporated the Golz Moulding Factor into the "configs" of the system.
You simply add a per foot charge to your moulding--anywhere from a few cents to dollars per foot.
This will take care of shipping costs, and it's an option you don't have to use if you don't want to.
Also remember: one of the number crunchers a few months ago in one of the mags proved mathematically that a 5% price increase to you does NOT mean you pass along 5% to the customer--it's more like 7-8%. For the life of me I can't find the article now, but at the time it made perfect sense.
