How can I change the size/colour/version of a purchased item?

Right now there's no option to change the size/colour/version of an item — you'll need to cancel the original order and repurchase the item. You can cancel your order within 2 hours after placing the order.

Here's how:

Go to My orders.
Select the order from the list.
Select Cancel order.
Select the cancellation reason, then – Confirm.

Your money will be refunded within 7 to 14 business days.
