new way to rwt!

Well I was thinking and thought of this!
Ok shops. They don't sell or buy any item for what there worth right?
Well if you were to say go to a unused general store with the second person and
a middle man. Then person A sells the item to the shop and person B buys the item for say 100k then sells the item in the ge for what ever its price is. This would work with rares, godswords, armors and more! Just please leave comments on this and if I have it in the wrong section please tell me!
Thank you for your time!

if i sold for example a santa to the general store, the buyback price would change to the middle price in GE. I know that when you sell it to the generale store, it goes for like 60 gp, but the buyback amidiatly changes...
that means it wouldnt work ;/

 

Exactly what he said. I tested this with an opulent table current market price 364k. I sold at general store for 2 gp. The buy back was 364k so this rwt system wouldn't work just as kn1fe says.

 

Yeah you sell a blue party hat there for 1 gp, and buy back for millions.

 

i beleive shop prices are based on the ge so this would not work

 

Yeah jagex saw people talking about this and patched it the same day as the grand exchange update.

 

Maybe you could buy from the General Store for mid price? Then sell back for Max price?
