i found 2 for 1 packs of sensodyne at the london drugs on 41st and victoria. its in the back on a separate metal rack located by the pads and tampons. Its on sale for $3.99, and if you have coupons, all the better to make it a better deal, but i didnt..but $2 a tube is still a great deal. its the regular sized of sensodyne (75ml?)
