Affordable adjustable dumbbells in Canada?

Hey all :)

My husband and I are new to FB but are really enjoying the workouts! We are currently doing FB Sweat and we've realized we really need dumbbells to get the most out of these workouts.

Unfortunately I find Canada is pretty limited retail wise for affordable dumbbells especially with the current crisis we've found Canadian Tire and Walmart so far are out of stock of dumbbells.

Does anyone have suggestions? We currently each have a set of two 4lbs weights each but that is definitely not enough when we are trying to up our weights in the same workout.

Any help would be greatly appreciated :)
