This has been going on for months, $5 raps, $3 bombers, and in soft plastics are $2 Yums which are mostly creatures.
Best suggestion is: Each walmart is different so travel to other ones around you and you might find all the other clearance items like spinnerbaits going for $1-2, strike king skirted jigs for $1, etc
I have to warn you though, not every walmart has a set price for clearance, so they vary.
