I want to send 100, but I want to do it cheaply... how do I do it?

I think you're best off hanging out at the Holiday Shop and restocking them. They're all around 4k at the moment. Usershops are about 3x more expensive than that from what I can tell.

They do go fast though, but now is a fairly quiet time, so you should be able to grab a good amount if you catch the restock. :)

I send up a trade for you...Lot - Description: Reserved for KillerCouch Free for you
