Online clearance items at Walmart will come in and go out of stock as they arrive in from the stores and are processed. You just have to be there at the right moment. As Franek did just plunk in your postal code to see if there are any at a local store.

I just randomly plunked in some postal codes in the GTA and a few showed stock for the wok on clearance @$6 in Brampton and Rexdale.
