RE: TROY BUILT MODELS
You can't win on shipping these days. It just gets higher and higher.
It's much worse when you send that stuff across your border into Canada. The rates you guys are talking about are quite low compared to the international stuff. Doesn't matter if it's through UPS or the USPS.
Don't forget that you also have that dimensional weight calculation, which is a way of cranking up the rate for whatever size box that you have by assigning an artificially higher weight to it to increase your charges.
Here, in Ontario, we also have the privilege of being able to bend over one more time and pay 13% tax on top of the shipping charge.
