Dollarama

I bought a thermometer for $4. When I needed to use it couple months later, I found out that it didn't function - the difference in the temperature was more than 1°c. And it's a lot, it means it'snot useful at all. And on the top of already not just $1 price (even for this price the item should be functional), dollarama has great policy - no refunds,, no even giving some store gift card.
And it's a second time when I buy not functional item and am refused to accept it back.
So amazing - just sell, make money and no responsibility for the quality. What a great business is created.
