This ensures that should the photofinisher have questions, a customer service representative can call you. Write any special instructions as clearly as possible on the envelope. Be sure not to write across the bar code. If you aren't sure how to fill out the envelope, especially the special instructions section, ask a counter person. In preparation of those times, be sure to purchase mailers ahead of time by visiting either your local retail location or camera shop.
Mailers are also available using mail order.
While away, simply fill the mailer out, enclose your film, and drop in your nearest mailbox. Upon your return, finished prints will be waiting your viewing. After viewing your prints and reliving those special moments, don't forget reprints and enlargements as gifts for friends and relatives. And Photo CD duplicates capturing highlights of your trip are perfect for sharing using your television set as a viewing screen.
