Why would them knowing the cost of a base material matter 1 iota to your pricing structure?
In my case it’s simply because of the competitive bid process with sophisticated, long-time buyers who have calculators.
In other cases it may be a new customer who is shopping vehicle-wraps and comparing quotes. His first peddler could have said; “My cost for x-brand, x-year vinyl is $xxx.xx.” Even that so-called knowledge can affect the price from the next guy for the same competitive reason.
