simple items like flax are trying to be sold on Besaid for 10k for regular and 20k for +1 i really hope no one buys em.
equipment seems to have an even/reasonable price at the min as do weapons.
Think it's just "what would i pay for that?" at the min and we all subconsiously are taking in prices from bazaars and setting them ourselves. new stuff will always be overpriced, people who want it 1st are willing to buy at rediculous pricing, wait a week and the price drops dramaticly.
it's all fluctuating but slowly settling for server prices, leve's are starting to give guild points instead of gil, think the low level ones are to help the newbs (yeah all of us :P) to get a head start, the further you progress the less gil rewards you will recieve" making you want to DOH DOL or DOW to gain items to sell, this will settle the economy too.
Common items for crafting will lower causing items crafted with them to be low, new items and craftable items depending or rarity will cost more making the finished item expencive.
Think this is what SE is trying to show us via the market wards. (with no ah you can't really see the supply and demand so prices stay steady, i think)
