I have a load of used mailers that you are welcome to have, I'll bring them along for you, ChrisI can bring along some recently acquired accessories to add to the party:
1. A Bob's Devices SUT which was sold to me by Martha's Dad last week and
2. An MIT speaker interface cable that will improve the articulation of your speakers, allegedly.
PS. If anyone has any spare 12" album mailers that they wouldn't mind donating my way that would be appreciated.
