Which is the Least Expensive Shipping Service to US?

[sylviebee]

I wasn't paying much attention, but I've just re-opened my store and not realize that CPO is in full on strike mode and not rotating this time.  Can someone tell me the least expensive courier to the US?  I've sold a few things and have an offer I'd like to accept but the couriers I've checked out so far are really pricey.  There must be some service that competes with CPO prices?

The Globe and Mail Report on Business has an update on the postal strike with some new background.

Like CPO which had a Q2 profit (before tax) if $46million had a Q3 loss of $319million (taxes not mentioned).
The Q3 report was Friday, just in time for the strike deadline, eh?

And as we already knew, while lettermail has dropped off, parcel mail has tripled.

And there is a sentence comparing the costs for delivery between CPO and one of the big couriers, which interestingly overlap.
And the reporter did not mention that CPO covers the entire country, including Old Crow and Joe Batt's Arm, while the couriers only work where it is profitable.

The article also mentions something that makes sense of why Intelcom is so ...erratic? Apparently there's no there there. The company subcontracts their management which in turns hires gig workers when and as needed and available.

I'd link to the article but the site is paywalled. Even with a print subscription I can't read the online articles.
