Depot doesn't charge shipping it's included in the price, Visions are tougher then the original and smoother.. The price is good too but shipping sucks unless you have a distributor near you.
If you an OfficeMax near you, that's where I get all my Iris tubs. I think in Canada, they operate as Grand & Toy but I'm not completely sure on that. Worth giving them a call as if memory serves there are tons of Grand & Toy's in the metro Toronto region.
Also check out some of the bed & kitchen type stores (Bed, Bath & Beyond type stores). They often stock Iris brand.
