Regarding shipping, because we use a third-party platform to calculate shipping rates, the rate you are quoted at checkout is only an estimate based on the average cost from across Canada and the US. If you order multiple items, an additional shipping fee may be applied if the total exceeds $5 more than what was estimated at checkout. We will email you to inform you of the increase in shipping fees before we pack your order. Our third-party shipping provider offers highly competitive rates; typically, we provide a small refund rather than incur any increases. We will refund any overages greater than $5.
