I recently ordered a bunch of CDs in cardboard jackets from CD Baby for an album I just released. I would like to be able to sell them online, but am unsure about the best way to go about shipping them. There are a lot of videos online for how to ship CDs in jewel cases (most say to use bubble wrap mailer envelopes), but I couldn't find any good guides on mailing CDs in cardboard cases.
Does anyone have any recommendations on how to mail CDs in cardboard sleeves? I'm considering something like this, but also don't want to deal with astronomical shipping charges. On a related note, the packaging (neither that envelope nor the the CD case) is not waterproof. How often does mail get wet in transit?
