it depends on what like style you want.. theres West49 for like skate, bluenotes for like cool stuff, like walmart/sears/zellers etc and then there are like thrift stores!
Threft Store, Good Will, any store that basically is hand-me-downs.. Those are always very cheap.
Walmart. I find alot of clothes at Walmart are as cheap as a second hand store.
