I've noticed a lot of HGI's won't let you buy newspapers with the $5 coupon.
Also, I haven't seen a chocolate bar for $2.5 anywhere other than the Pavilion Pantry. Gauging on the "freebies?"
HGI YUL lucked out on an upgrade, plus the $5 coupon, can't complain there.
Haven't seen condoms recently, but I do remember seeing them somewhere.
