Guys this is obvious but thought I would share just in case
To save yourself a bit of gold and store more items I have done the following:
I have created 4x alts to use as bankers and called them:
1) Intelligence
2) Dexterity
3) Strength
4) Gems
I then fill the stash with all the rares and items I am keeping and then log in with the relevant ALT to collect.
You can easily view what they all have by going into the AH sell tab and click on the various ALT's on the right side - where it shows their bag contents.
hope this helps someone
