I have a Radley one - half price in the sale in the summer. Worth keeping an eye out for their next sale as they are a bit more affordable then (only a bit!). It is good quality and am hopeful it will last and last - hope so 'cos I went into it as an investment piece!
I got one from Staples a couple of years ago. HUGE plain black leather, easily takes a standard 'school' laptop and a4 folders. Has central zipped section and internal small pockets. Handles are long enough to go over my shoulder but short enough to hold in my hand too. Was £70-80ish :-)
So it's nearly September. I don't need any new pens or lovely notepads but I'd like a new bag. (Sad? Me?) I need it to hold a laptop and planner. I'm thinking a smart one (leather?) for parent meetings etc. Radley seems to come in at about £200. Ouch?! <poor p/time teacher emoticon> Any ideas?
