On Thursday, I start in the Red Hall because there is a dealer there that always has stuff I like at prices I really like. The good stuff is usually gone pretty quickly, so I make a point to go there first.
Then I hit Orange, Brown, Purple, White, Blue and Silver, pretty much in that order.
On Fridays, I go where the wind takes me. By then, I have done my serious buying and on Fridays I look for the impulse items.
