Buying and selling items seond hand does a lot of good. It saves money, obviously, but it also extends the life of items and makes them valuable to new users instead of ending up in landfills. Canada's second-hand economy is particularly strong according to Kijiji, with 2.3 billion items changing hands last year.

If you buy and sell second-hand items, you can put almost $2,000 in your pocket over the course of a year (actual total $1,959), according to Kijiji's fourth annual Second-Hand Economy Index. That's more than the average annual pay increase for full-time employees in Canada ($1,729) simply through savings from buying second-hand and money earned from selling unwanted items.

An estimated $28.5 billion worth of second-hand items changed hands in 2017 and more Canadians than ever – 85 per cent of us – are getting in on the action in one form or another. This includes buying or selling, along with swapping, renting or donating second-hand items.
