Wedding invitation prices vary based on the number of recipients, the level of detailing, and the postage required. Some sources say that, on average, brides spend anywhere from $5,000 to $8,000 for roughly 100 potential wedding guests. Others, like Shutterfly, say that those figures are closer to the $500 mark. Either way, homemade wedding invitations have those all beat. Depending on what look and feel you’d like your invitations to have, you can easily make yours for free (if you go the digital route) or cheap ($50 for simple yet elegant designs plus 3 books of stamps).
