Its there to sell. When you sell loot to the Stores, new items pop up in the Bazzar. like when you sell 5 behemoth Steaks, the bazzar sells you 50 x-potions for 4444 gill. some stuff like that is good, Or you can pick up the MASAMUNE from the bazzar for 2 Gemsteel, 2 orihalcum, and 2 mallets. its just items you find from monsters, which is why you try to fill out the biastary. In the bistary, it says what some people drop, in blue letters. its really cool, or something it can be a pain in the butt. like getting Omega Badge (beating Omega mark XII), Lu Shang Bagde (Fishing side quest) and the GodSlayers Badge (for beating Yiazmat) To get the stupid Wyrmhero blade...(EVasion +50, Str +130)
