I bought a hybrid bike for touring May 2016. It’s in Calgary. I’ll be doing some Rocky mountain biking in August.
July 2016 I bought a second identical bike to be stored in Parksville, BC at my parent’s place. (I’ll now have a mountain bike and a hybrid in each city.)
I got the second on sale for $550 as it’s now last year’s model. It would have cost me well over $100 to ship a bike Calgary to Parksville. And another $100+ to ship it back. THAT’s the good reason. It’s less expensive for me to own two bikes than to ship one back and forth.
I’ll be cycling a lot both out of Calgary and Parksville on the two bikes.
However … MEC bungled my order for the $550 last-year’s-model. Instead I had to buy this year’s model now $775. AND I needed to accessorize twice. Quite costly.
