I feel cheated after buying the product on Apple.ca

Yeah, I can explain it. It’s common business practice. Apple does not control what other retailers charge for their products. There’s this thing called a profit ‘margin’. Have you heard of it? If an authorized Apple reseller like Amazon wants to give up some its margin to sell a product for less than Apple does they can do that. Apple is not required to match prices with any third party retailer. Feel cheated if you want, but you weren’t cheated. Return the ones you purchased from Apple for a refund. You have 14 days from the date of purchase. Buy whatever you want from Amazon.

Third party resellers are free to set their own prices.

Amazon discounted the price.

Apple sold them at regular price.

There is nothing to explain.
