@boomerang,
Candy for the fella, and dog treats. There's a store here called HomeSense - it's part of the TJ Maxx group - they clear their seasonal dog treats out on Boxing Day - stuff that was $10 - $20 will be $ 1 - $3.
I used to always go to the Reebok/Rockport outlet on Boxing Day as well, but there isn't one really close to me here. Awesome awesome sales on really really good shoes and sporting gear. I got $200+ golf shoes for $10 one year (and the second pair was 1/2 price - so $400 of golf shoes for $15 - works for me).
