From client: "Never mind, i had to pay a lot of money to have one card shipped. I will scan it." - how we can avoid this

Move to a different niche? They can’t scan t-shirts, coffee mugs, tote bags, pillows, etc.

Or, make a requirement that customers must pay for a minimum number of invitations (like sets of 10 or 25 invitations?

I don't have any answers. I am sorry, though. I can't believe the person would actually admit this freely in a comment to you. Wow. 😞

If they mean scan your products directly off the Zazzle website, you can choose to use the water-mark option in your account settings.  That will discourage some less tech savvy people; not all. And you might not like the display look. Really, if people want to be cheap and dishonest, there's nothing we can do to block them.

those kind people dont worry even about watermarks

I was really upset to read that… unfortunately  we can’t do much to prevent it if customers are not sensitive to the quality of professional printing of an original creation enough to avoid bad copies. What I would suggest is to create mores specific cards  for example gold foil, round corners where the copy is more difficult… ( not special papers because Zazzle look like they want to remove them )

It can't be avoided, not here and not anywhere in the art world these days. Lawsuits for theft are all over the place. What you can do is think about all the customers who helped push you up to Pro Gold status, the honest and appreciative customers who paid for your hard work. Focus on them and keep yourself happy because they're the majority.
