Greeting cards, stationery for my son, lithium watch/light batteries, cheap beach/pool toys for trips, cat litter deodorizer and toys etc....things that are cheaper there than Walmart.
So for me, the "no return" policy doesn't affect me one bit.
Why people buy stuff there with an expectation of it lasting is beyond me. Electronics, tools etc.
Like the "Dollarama hidden gems thread".....it's mostly trash
