This allows you to buy as many items as you want (256 is the limit I think)
And of course If you don't have enough money for the items it won't work
1. Open tsearch and target EO
2. Go to a shop and press ok on 1 item
3. Don't buy the item all the way!
4. Search 1
5. Press ok on 4 items
6. Search 4
7. Continue steps 2-6 untill you find the value
8. Freeze the value at whatever you want and then buy it.
I hope it works!
