We can typically combine orders before they are shipped out provided we are given adequate notice. Simply place a new order for the products you would like to add and indicate in the checkout notes that you wish to combine them with a previous order. When you receive the confirmation email for the new order, please reply to it in order to draw our staff's attention to the request. Our staff will be able to refund any necessary shipping charges when the orders are combined.
If more than a couple of hours have elapsed since you placed the first order, please phone us first at 416-599-6447 to make sure that we will be able to accommodate your request. If you are simply adding items to a pre-order that will be shipped in the future then calling us is not necessary.
