I noticed this little trick to get free international delivery being discussed again in the It Takes Two deal, and realised I haven't seen it posted as a deal before so I thought I'd post one.
It's been known for a while now to some, but for those who don't know what to do, simply add a different item (or multiple) sold by Amazon US or UK to your cart to hit the $49 minimum spend and place your order, then cancel those items and you'll still get free shipping for the item/s you want.
Mod: The OP has asked us to remove the deal, due to the reception it has received from some members. However we have kept it published, as it appears to be of benefit to many. Thanks
Do I need to sign up to prime first and find items that offer free shipping?
