- Instructions
Card Mailer prints 5x7 photo postcards (no envelope) and mails them by USPS First-Class to US addresses. Typical flow: -> -> -> (returns a link where the user pays on cards.onmax.me) -> . When the user asks for a card preview and price, call first, then pass its design_id with list_id to so the final widget shows both card faces and the quote. After editing a design, quote that same design_id again to show its current preview and price. Nothing is printed or charged until the user pays on that page. US addresses only. For holiday, thank-you and other personal or client greeting cards; not for e-cards, email, or advertising mail.
