I made some dvd's of a recent getaway trip with friends and wanted everyone to have a keepsake from the trip. Between the cost of the dvd and the mailer and postage it was about [$] for each person. It is inexpensive enough that I didn't feel I needed to be reimbursed for my investment and will be something that they can enjoy for years to come. Plus you could probably use the same mailer again by covering over the address with a mailing sticker and stapling and taping the "open" end.
