How do you temporarily change the shipping location?
If you’re logged in via Amazon, this should work (I did it on the desktop browser version but hopefully it will work in the app, too):
Go through the checkout process until you reach the final page that has the ‘place your order’ button. It will also show your shipping address and a link to change it. Click/tap on that and if the address is already listed, select the one you want. If it isn’t, go down to the bottom and choose to add an address.
It’s probably something similar if you’re using the Woot login.
(Please note: I don’t work for Woot, I just volunteer to help out here on the forums.)
Just remember to change it back before your next order. we can’t change addresses on orders.
