Back-to-school shopping spree?

I know it's a little too early to be getting ready for a back-to-school shopping spree but it's good to be prepared, right? I'm going into junior high next year (7th grade for me). Anyway, what's a good price range? What brands should I shop at? I was thinking Abercrombie, Hollister, Aeropostle, American Eagle, Forever 21, Delia's, North Face, UGG Australia, etc. Will they have a back-to-school sale? How many stuff should I get? For example, how many pairs of shoes should I get or how many shirts. Please make a list of how many things I should get; maybe even say what kind of accessories I should get, what kind of shoes, etc. What kind of brand for school supplies should I get? Please help, thanks!! :)
