The biggest question I usually get asked about invitations is how much do custom suites cost. And unfortunately, it's really difficult to give a broad estimate because so much of the cost is dependent on the order. Digital printing, letterpress printing, and hot foil printing all vary in cost. Even the type of paper can change the cost of the suite.
Couple usually spend between $500-$800 for their invitation suites. If you have an idea about what you're looking for or want a more personalized quote I'd be happy to help!
