I use both GoingPrice Allakazam Data Source and GoingPrice Wowhead Data Source. Why are the prices they produce so greatly different? If they're both recording what peoples' stuff is actually being sold at, why aren't they coming up with the same numbers? I can't believe that Allakazam contributors are better or worse "businesspeople" than Wowhead contributors.
you also gota assume one of them is just going by the AH prices listed and not whether it really sold or not (since you dont know if someone bought it or the auction expired). so i would guess allakazam may be going by what a given person won the auction for and not the listed prices.
