On a side note, I have been investing heavily into Lucky Charm to see if it is a viable solution for economics in this game. So far, it's somewhat hit & miss. You get a lot of nice equipment but:

+ most of the time it's lower level than your currently level. I guess you get n-level gear depending on the area you are currently exploring.
+ It's pretty RNG, although not as bad as it may seem.

So in the end I keep trading a lot. Browsing through endless inventories/shops is annoying and very time consuming.

PS - Why stores don't have an option to SORT gear BY LEVEL?
