( Internal )

The script updates item prices (buy/sell) for an item vnum:

Considering item vnum is 110, it can update till 119 (or starting vnum 112 can go till 115, or 117, or w/e you desire)
It can update for a single vnum (upgrade items, aswell), more in comments below 

Combined with can be pretty efficient
