Yes, you have mentioned 3rd party shippers before. Again, if recall, ended up being what I would call moderate discount over mainstream methods. When I input numbers into their rate calculators it was only marginally better. Whenever it crosses borders, someone has to process it through customs, either paying duty & taxes on your behalf or otherwise clearing it for you to pay after the fact. Its had to imagine they would do this for free, but if they do it for $10 instead of $45 I'm interested.
My conclusion, at least from the 3rd party links you provided last time, was savings was more related to aspects of your BUSINESS - shipping volume, rate negotiation. larger volume accounts or whatever. Its great that you do this & savings flow through to the business bottom line, but we are talking about receiving goods (as in onsey-twosey) from USA to a regular individual, simple as that. Not shipping goods from Canada outbound related to a business.
But back to your statement For all to learn, UPS World Wide Expedited includes brokerage lesser, cheaper services don't. The same goes goes for all the other services out there.
Can you show us an example using UPS price schedules how everyday Joe can save money using UPS-WWE vs. other modes importing an item from USA?
