The Holiday Bazaar is a bazaar in Greg's city from where he buys things for the holidays. Greg found out that they were selling over-priced Drummies, so he thought of buying many cheap ones from another shop. Greg and Rowley started their own Holiday Bazaar after this. The Neighborhood Tattler busted the original Holiday Bazaar for selling over-priced Drummies, that's what originally caused Greg and Rowley to start their own Bazaar. They wrote about it in their newspaper.
