Don't know if you have heard Listia just started a new delivery option for emailing items
Digital Delivery
When listing digital items such as e-books, pdf files, digital photos, codes, electronic gift cards, or any other digital item will be transferred online, you must select the "digital delivery" option. This will help people find your items and prevent confusion about whether the item will be shipped physically or delivered electronically. Additionally, digital items should not be listed with physical delivery options such as "free shipping" or "local pickup" and must abide by all other rules regarding ownership, copyright, etc.
Listings with incorrect delivery options may be edited or deleted.
