It's really simple, make the item not resellable for 72 hours. This has minimum impact on regular players.
85 Tauren Druid Restoration/Feral Spec complete with Ruthless Gladiator Leather set and Staff along with all PvP accesories. Includes PvE Armor as well, including Raid Finder Polearm as well as highest Flight Available and many mounts, including Heart of the Aspects. On Khaz Modan Server, complete with FIVE COMPLETE HEIRLOOM SETS, INCLUDING EIGHT HEIRLOOM WEAPONS, available immediately for creation of alts. Also includes two Alliance characters on Suramar 85 Gnome Mage Arcane/Fire Spec with complete Ruthless Gladiator PvP set and 74 Human Death Knight complete with Brutal Gladiator PvP set.http://www.3zoom.com/WOW(US)/cheap-account-8.html
Also, you can have a incremental timer after some number of buys/sells, the timer increases. Start with 1 hour, and for every item bought/sold increase it by 1 hour (or some number that you feel is right).

Thanks^^
