Yikes, UPS was disappointing (cursed inflation!). I took a planner and calendar I had of similar size and weight and it was going to be $39. I did get a quote online for the postal service of $23-30 and I can verify that on Monday in person if you'd like.
I wonder, since you two are in the same province, would it come out cheaper to split the shipping for one package with both calendars and then the recipient mails it to the other person? I saw that they're being offered as a discounted bundle at https://greytstore.org/products/celebrating-greyhounds-2024-wall-calendar-weekly-planner (not sure if they ship to Canada, but I'd be happy to order and ship if this idea makes any sense at all).
