I, too, wish I could order items. A riding mower tire on Amazon.ca is $138. On Amazon.com it is $53. Just have to wait until border reopens for travel and non-essential services. "
I'm assuming the $53 is in USD. With today's exchange rate, that's $68. If both are Amazon, I'll assume it will qualify for free shipping either way.
If you're driving from Brandon to cross as Bossivain, it's roughly 100 km each way, so a 200 km round trip.
If you're driving a Honda Civic, with a highway fuel rating of 8.4 L/100km, you'll need roughly 17L of fuel to make the trip. Gas is around 104.9, so you'll need about $18 fuel to make the trip. If you drive something more like an F-150, you'll use $23-25 fuel. That's not including the cost of wear and tear on your vehicle, or the cost of any food/rest stops you make.
So, without accounting for your time, it will cost you $86-93 for your tire if you order from Amazon.com vs. .ca.
If you paid yourself for your time, with min wage being 11.65/hour, with a trip time of 3 hours (to allow time to get through customs etc), you should "pay" yourself $35 for the trip.
So now you're at $128.
I frankly would just order it from .ca and get it delivered to my house.
