Group buy simply means that a group of 10 or more gets extra savings, but only for 6 days. Your order is received and shipped separately, nothing group about it. They ship UPS, but they pay the brokerage fees. You pay the HST up front. There is a $5.00 discount on shipping if you order more than $175.00. You can add items to your cart and get a shipping quote if you want to know how much. Orders for Canada only ship on Fridays though.
