I've never seen trading cards on clearance at Target or Walmart.
Don't forget, those stores don't own any inventory of trading card product. That shelf space is rented by a local vendor who comes in and puts their own inventory out for sale. I'm prety sure they have other outlets for items they might need to 'clearance'.
