You're hoping to jump into a quick profit I see but this item barely came out today. You'll have to wait until they are not buyable through tokens. Also blizz ards have rare chance to drop Avalauncher. Seeing as these have no year variant, and will likely be released every year. They won't attain massive value unlike the older ones that clearly state 2014 in their lore.
there's one being auctioned off right now http://empireminecraft.com/threads/auction-avalauncher.60450/page-2
He just wants to know what they're selling for now. Kind of unrelated, but no wise reseller would sell while it is still on release. Knowing what they are priced at currently sets the minimum ground for where you can begin to profit in the future.
