I've tried selling them on red alts on this server and usually get a lot of /ignore or report player for cheating 'cause loot code pets had to be redeemed via code.
I can now redeem the pets, myself, box them up, and sell them direct without having people freak out that I'm trying to rip them off with a code redemption. I'm not, however, going to redeem a bunch pets on red side if there's no demand.
Anyone on the red side want Purple Puffers, Sand Scarabs, Eye of the Legion pets? I may also be able to scrounge up some Landro's Lil XTs and Landro's Lichlings if there's a demand.
