Here is a more detailed example of my idea:
Saradomin
opens the Grand Exchange window and
selects the sell option, selecting to sell 10k feathers from his inventory for 10gp each
. After confirming his offer,
Saradomin's offer is listed in the Grand Exchange
.
Zamorak
then opens the Grand Exchange window and
selects the buy option, selecting to buy 15k feathers for 5gp each
. After confirming his offer,
Zamorak's offer is listed in the Grand Exchange
.
Guthix
opens the Grand Exchange and
selects the browse offers option
, entering the item name feathers and he is taken to a window where
he can browse all current trade offers on feathers listed in the Grand Exchange
, and he is able to see that
Saradomin is offering to sell 10k feathers at 10gp ea for a total of 100k
and that
Zamorak is offering to buy 15k feathers at 5gp ea for a total of 75k
.
Since Guthix needs to buy feathers, he selects Saradomin's offer, but only buys 5k feathers at 10gp ea for a total of 50k
.
Zaros
finally opens the Grand Exchange and
selects the browse offers option
, entering the item name feathers and he is taken to a window
where he can browse all current trade offers on feathers listed in the Grand Exchange
, and he is able to see that
Saradomin is offering to sell 5k feathers at 10gp ea for a total of 50k
and that
Zamorak is still offering to buy 15k feathers at 5gp ea for a total of 75k
.
Since Zaros needs to sell feathers, he selects Zamorak's offer
, and since he is the Empty Lord, he doesn't care about how much he makes
and sells Zamorak 15k feathers at 5gp ea for a total of 75k
.
I hope this detailed example helps clear up some questions about this idea.
