To date, what's the most expensive item you've purchased for your collection? Is it a rare action figure or maybe a quality "collectable?" Did you maybe put together an entire Stormtrooper costume or assemble a collection of soda cans or trading cards?
With that in mind, what do you think you've spent on everything Star Wars so far in your life? Given current prices, can you project what you think you'll spend from here on out?
(by the way, I have to put a little thought into the questions myself...)
