I'm starting a degree next week 
. I have a rucksack but would like to find a nice bag. My requirements ideally are:
Both shoulder and crossbody straps
Fairly sturdy and structured
Will hold a textbook, a4 notepad, a5 diary, purse,laptop, possibly lunch and work uniform. (Plus all the other crap that always ends up in a handbag)
Cheap as possible. Ideally no more than 30 pounds.
Has anyone seen/bought one recently that fits most of that? I'm looking on line but I have no spatial awareness whatsoever so finding it very hard to visualise.
Thanks in advance :)
