Well if you need costumes or accessories, they are on sale. Some style of pj's as well were 12.99. The vaughan mills had lots of children t-shirts for $3.99. Happy shopping!
Was in Burnaby Metrotown last night and costumes were 50% off (some 40 off). Lots of baby clothes marked down, but not super cheap. A few other sales, but nothing notable.
As someone already mentioned...costumes and accessories are now 40% off, with the exception of Tinkerbell, which is 25%. I got some nice children's tshirts for $3.99.
