I've always felt that the customer deserves to know what this is going to cost "out-the-door".
Bidding something at $1,500 to get the job, and then adding set-up charges, inventory pull charges, minimum "per-function" charges, etc. to where the final cost was $3,000 just rubbed me the wrong way.
Did a small stint in sales for a very large print & mail shop where I was eventually let go due to getting sideways with the sales manager over that very thing.
But, at the end of the day, we all have to live with the man in the mirror.......... It all worked out for the best. I went on to do bigger and better things, and that "very large print & mail shop" is now a very small shell of its former self just barely hanging on.
