For all you Canadian's: Canadian Tire started to sell an interlocking floor tile, standard 12" in grey only. I was in the store one day and opened up a box, layed a few tiles on the ground and snapped them together. The material seemd very brittle, they weighed next to nothing and were kind of thin - but they were cheap. Anyways I started to seperate them as I have done with my Race Deck and every loop snapped off at the same time, not once but three times! While I was making this mess a store manager saw me and asked if I planned on paying for what I had broken. I said sure but only if you can seperate these without breaking them. Well he broke two more, then said maybe they are not supposed to come appart!
