Looking through the items available through the weapon vendor in IQ, when I spot a banishing rapier.
I double click to pull said rapier to my to buy area, and go through the rest of the list.
In the time (20 Seconds) it takes to look through the rest of the list, someone else purchased the rapier.
Wouldn't it make sense to have a record reservation for that item if you pull it from the list to the area where you can purchase it?
The reservation could disappear by purchasing, or clearing buy area of screen.
I know I should have purchased right away, but have learnt that now.
