Not sure a thread about trackies goes under "Fashion" but anyhoooo

I am teaching PE now, and am wondering where the best place is to buy reasonable priced trackies and sporty stuff - I am not looking at professional stuff, more just nice comfortable and warm stuff to wear that looks decent as the Bonds trackie and skinny leg trackies that I wear at home are not "school appropriate!".

I also really don't want to be paying $60-$80 for tracksuit pants at places like Rebel!!

SO any ideas please! Going to check out the majors but there might be some places I haven't thought of!
