What is the nature of the defect?
When you buy an ingredient with GW
it counts the items it has bought against the total needed and shows them as in the mail.
It happens though that an item could not be found because it has been bought out between
the scan by GW and the buyout.
These auctions give an error when trying to buy them "Item cannot be found"
which is ignored by GW.
The item counts as in the mail.

yeah, if you run out of money it also thinks you bought it.  i need to hook the actual "you won an auction" message to verify a successful sale.

Can be setup a MAXIMUM gold per item bought ?

some times you have a lot of items like 1g,1g,1g,1g,1g and with you click so much appear one at 100g with a “please ignore all up from XX gold without pressing a modifier like shift” will be helpful alot.

yeah, i think some kind of heuristic would be good.

i want to make the scanner display some basic stats about the cost of the item (if available) so you can see if the prices are good or not based on market information (from lsw).

in general, i'd like to add a step in the process to allow you to "unlock" the items you want to buy first, only "unlocked" items could be purchased with a single click.  perhaps gw would start off by having the suggested lots be "unlocked" to begin with.  so the work flow would be to scan, then click on the individual items in the shopping list to select them in the purchasing window, and then buy what's suggested with single clicks.  optionally, you could unlock lots of items by mass selecting them and clicking an unlock button.  perhaps a modified click would let you buy outside the locked items if you just want to grab one and a different modifier would be need to buy something that's way over-priced.

my goal for the purchasing agent is to make it as quick as possible to buy reagents without making it too easy to accidentally buy something wrong.
