March 7 Update: It appears the dates have been pushed back. The earliest stores will begin their liquidation on March 14. (thanks unclephn)
If you are not aware yet, Zellers Canada will be starting their first wave of store liquidation starting from March 8-16 depending on your store. Everything in their stores must go so this may be your time to grab some LEGO bargains! All of these stores will be closed sometime in June 2012. Complete list of stores here.
For those that do not know, the top performing Zellers stores leases have been purchased by Target (US). These Zellers stores will be converted to Target sometime in 2013 and 2014.
