I have a shopping buddy, I call it old man trolley. I drag and push it all the way to shopping center, inside the shopping center, and back home. It doesn't look pretty, and I bought it from a two dollar shop with cheap price, just for the time being before I get a car. It is very useful and it doesn't know afraid a little bit of rain.
Today, I took it for grocery shopping again. I bought a bucket, some gardening stuff, a 2L coke (only costs AUD1.95, on discount), and few other things. Everything was put inside my old man trolley without any problem.
