If your order hasn't shipped yet, simply email your order number, full name and new address (if you are changing your address details) to hello@alpakagear.com. Orders tend to ship 1-2 business days after an order is placed and once an order has shipped, we are unable to make any changes. Even if your order has not shipped yet, it may still be too late to make any updates to your order. Once shipped, it is impossible for us to change the delivery address, cancel the order, or upgrade the shipping. Thank you for understanding.
