I found I could save just a bit over a dollar on several packages. Rather than buying Fruit of the Loom underwear at the uptown Walmart, it was cheaper to order on Amazon.ca and have them delivered right to my own door. Sure, why not? This is not the type of merchandise one must evaluate in person, nor would I have been able to open up the packages in the store anyway.

When I got home from uptown yesterday I found an Amazon box in front of my door. Because of where I live, paying extra for Prime delivery is not necessary. When I choose the 'free shipping' option, I generally get my merchandise within two working-days.
Of course, I found several more things I could use and the box also had a pair of travel binoculars and some USB to USB-c cables. These will be necessary for a new mobile phone. So, it was nearly as easy to pick up unplanned purchases on their site as when in a physical store.
Why bother traipsing around a mall?
