My pricing is exactly the same - $7.50 or $15. If I am selling them the plaque, I offer to allow them to pay for updating in advance at $4.50 per plate. Pretty good deal because we rarely do every plate on the plaque - hehe. Sadly, these plaques don't get 'perpetuated' for long, most of the time. Although, I have a couple of corporate customers that would rather pay in advance then have to pay $7.50 each time and they DO fill up their plaques year after year.

I have always struggled with what to charge when I have to make a new perpetual plate that requires drilling and attaching. Lately I have been charging $4 a hole for drilling and attaching or $31 for a plate that will have several names on it. This is based on $15 to engrave and $4 per hole.
