Since you can store inifite items sending them to yourself and then return them to yourself from your mog house..its a nice method, but it can take some time. This will save you a little time with it.

There is a command to open your delivery box, it is /deliverybox.

Go to the delivery NPC near the AH and send yourself what you want to store. Use the /deliverybox command to open your box and receive them. Then just finish the process. This can save you a little time.
