The advantage of setting courier contracts from the "Market deliveries" hangar is that it is counted as a corp hangar and so when it is hauled it will be delivered to the "Market deliveries" hangar in the target station and so accessible by any member of your corp. This is a better idea than setting up the courier contract from your own "Item hangar" and so when it is delivered you then have to "item exchange" from your char to either the corp or another char - all very tedious.
However, if you want to split items in the hangar it can not easily be done. i.e. lets say i want to split my Plex into a stack of 34 and a stack of 60.
For example, in the image below i am unable to split my 94 Plex in my "Market deliveries" hangar - if i try the standard shift+Left click and try to split the stack then i get the Access Denied warning:
The "Market Deliveries" hangar is not technically a corp hangar. The only way to get items into the hangar is to either buy from the market using corp funds or to set an "item exchange" contact up with your own corporation (and even then you need another char (preferably on another account to do this quickly) to accept the items into the corp and so into the Market deliveries hangar). You can set up courier contracts from the "Market Deliveries" hangar which will be delivered to the "Market Deliveries" hangar in the station hauled to.
Fortunately, i have discovered how to split stacks in the "Market deliveries" hangar.
- Right-click the item >>>> Create Contract
- On Page 1/4 of the Create Contract window: Select "Item Exchange" and "My Corporation"
- On Page 2/4 right-click the item and select "Split Stack", as shown below
- You can then split the stack as required
- Then press Cancel on the Create Contract window
(edit: corrected spelling of "hangar")
