This is a simple, realistic, human emulating, auto seller. Basically people are lazy. Who wants to move there mouse? Scripts don't care and will sell 100k items the hard way.
My approach on this was laziness. What would i do if i wanted to sell loads of items to the store? Well the answer is simple.
I put the item in the bottom left corner of my inventory, and change the mouse buttons to 1. Then i take the mouse ball out and click like mad while i watch tv or something.
DIRECTIONS:
* Set mouse buttons to "one" within runescape.
* Place the item to be sold into the bottom left corner of your inventory (first column, last row).
* Open the store.
* Run the script.
* Untested with stackable items other than notes. Should work with runes, my only concern is arrows because it uses getcolor on a spot arrows may not cover up.
Never had it drop items while not in store. It constantly checks for orange store text.
it's short so i'll just paste it:
