I just noticed that the way the bazaar applies your credit perks rounds the decimal value of what ever is being sold to the bazaar. I always assumed it retained a hidden decimal value, but it does not.
Godly Health and Mana Potions sell for 20c and 40c respectively with no bonuses. The new item values are calculated from your perks and then rounded before being multiplied by however many you're selling. I've got Short Seller, which gives a 16% bonus to everything sold to the Bazaar, making the new values of Godly Health and Mana Potions 23.2c and 46.4c, which are rounded to 23c and 46c. Normally, you'd think, ".2c and .4c per pot is no big deal," but you'd be surprised how much it adds up when you're selling thousands. It would literally "Short Sell" me my thousands of credits.
Basically, anyone with credit perks short of Golden Handshake is probably being ripped off by the Bazaar. Why not Golden Handshake? Everything with a base value above 10c would result in whole numbers. All the other perks would give you a credit bonus with a non-zero hundredths value, i.e. 1.04, 1.08, 1.12, 1.16, resulting in rounding discrepancies. I haven't done the numbers on the other perks, but rounding with Short Seller definitely rips you off on the most important items, the Godly Potions.

Crap... crystals are counted as arena bonuses too? I don't think I've ever had a crystal for an arena clear bonus.
Wish the arena clear equip bonus would increase to something like 75% for Sealed Power -> Eve of Death.
This whole game is basically about dangling a carrot in front of the proverbial horse, and then giving it the middle finger.
