Buying and returning without using something is fine. But most people here dont, they use the item. And dont get me wrong I love the return policy. I once bought an Armani Suit and after a week decided I did not like it so back it went. Sure, its wonderful for us, bad for the store.
I dont know about Canada but here its 90 days with or without receipt in most cases. I dont see many 14 day policies its usually 90 days. People buy clothes, wear them for 3 months and on the last day they return it for full credit. They also buy computers, TVs, and return it on the last day after using it for 3 months, they go to another store, buy, and return 3 months later.
So in one year they get 4 new TVs and pay 0 while the store has to accept the return of the computer, TV, clothes, etc. The consumer can go for years enjoying new products and never paying for anything!
When you go to Target, Walmart, Best Buy, etc you can see these people for yourself.
