what? what shop list? they're arranged by cheapest item first in the user shop search. or do you mean the main shops?
They're organized by shop ID. Which kind of makes more sense to me from a coding standpoint. I guess alphabetized would be nice, but...I'm kind of neutral on this. Doesn't take long to learn where in the list the shops you use the most are, and it's not so long that you have to spend a long time digging for unfamiliar ones.
