price check is what people always want to do when they want to sell item either bazaar or retainer. But it is annoying for active crafters who always sell a lot of stuffs and have to go to the corner of market to check price then come back to put each item every time.

In some online game, when you put item in the retainer, and you are setting the price to sell, they will have another option that will check current market price for you instantly, so you don't have to check market price manually and be able to put your price right away.

I think it will be cool to have this in FF14 too. This will make money flow better and market become more active.
