Help creating shop

[geekbar21]

Im trying to make a shop that would either require an item or other in game currency thats not eps or gold.
soulnecturn stated somewhere to refer to the actions of buying hair/avatar but im finding no lead

[Kaos2018]

1655 -> Exchange store or NPC + Actions
Classic -> NPC + Actions

[geekbar21]

im not following the relation for old engine
the actions in the guide dont even show types/params related to what im looking for
unless im missing something

[magewarior2]

oh yes in the 1655 there is an option for that,

cq_exchangegoods

id = id number
ownerid = Shop ID, Use NPC ID for this.
itemtype = Item ID
Price = How many of "needitem" you would like to exchange.
maxcount = Set to -1 for unlimited MAX is 999 DO NOT GO OVER

in cq_action => TYPE = 250 / Data 601 (also add this ID into cq_task)
