cheapest USPS mail forwarder?

[dude4]

i have a small package i want to forward to my address in calgary
Shipping dimensions are: 16" x 4" x 7" and weight will be around half a pound

i don't really want to rent a mailbox or pay a subscription i don't get mail from there often, so id rather pay by the package
any recommendations are welcome

thanks

UPS Store on 10 Ave S in Great Falls.
I'm not sure how much per package receive rates are, but they're awesome.
I've had a box there for probably 8 years now.

Call them and work something out.

Although.... I'm not sure they'll forward without you visiting there first.
