Here in Canada, I find the prices pretty neck and neck. Small items tend to be a bit cheaper at the stores, since there is very little overhead for them to carry small items compared to Amazon’s picking and delivery logistics. Big items tend to be a bit cheaper on Amazon. For tech specifically, Best Buy price matches items, so it’s not that bad… Memory express and CC sometimes have lower prices than Amazon too (see PCPartPicker).

The main reason to use Amazon is you can easily find some really obscure stuff. Then again, you can buy direct from manufacturer, like Vevor, for often cheaper.
