I sell wedding invitations that I designed on Zazzle, which I personalize with the couple's names, date, and colors for a $30 design fee. If the couple wants the same art placed on other items on Zazzle (like matching RSVPs, labels, magnets, etc), I'll set those up for no additional charge since I'm going to make my real money when they order the printing. This process has worked great for about 3 years now.
I have had several times where the couple requested the artwork for things like their website, custom glassware, even cakes, and I have either charged reasonably for the art or just provided it directly to the vendor. However, I now have a couple that wants to give my artwork to another designer to design and print their invitation! I'm a little upset since they already purchased Save the Dates from me, and they know that I design invitations as part of my living. They have given my contact info directly to the other designer, who is now directly asking me for art. I've never been in this situation before .
What would you guys do? Flat out tell them "No", or release the artwork but charge a fee? If you think I should charge a fee, how much do you think is appropriate?
