Who knows where I can buy a heavy duty shopping cart? I live close enough to my supermarket that I usually do a big trip every couple of weeks but I'm always overloading my shopping cart with heavy stuff like potatoes and beer. I had one of those 49 zł two-wheel canvas-and-aluminium carts from Auchan but last week one of the wheels broke off and I really need something tougher. Something made of steel. Something with strong wheels. Something that can carry 25kg. Anyone know where I can go to look at a selection of tough trollies in Warsaw?
