Other Tips for Using the Bazaar

Avy'enda of Starsider reminds all players that the maximum amount you can sell an item for on the public bazaar is 20,000 credits. Avy'enda sees a lot of new players put their item or painting - many times worth a million credits or more - on the bazaar for auction, hoping it will bring market value. Unfortunately for them, there is a cap of 20,000 credits for a sales price on the bazaar. So whichever savvy rich veteran player goes in and bids 20,000 credits first is going to get the item and the seller will have just lost out on 980,000 credits (/comfort n00b). For premium items, you are better off listing it on your private vendor, or else posting it for sale on the official forums in your galaxy's trade forum.

When using the bazaar, Halo of Tempest points out that you can also search player-placed vendors that are publicly listed by clicking the vendor search tab at the top of the screen. With the new bazaar enhancements, you can find some awesome deals out there. You can't actually buy items from vendors on the bazaar, but you can get a waypoint to the vendor and fly there fast so you don't miss out on a great deal.
