Go to a thrift store where they have boxes full of power cords and rummage through it to find what you need. Some goodwill stores are like that. It seems like they purposely separate removable cords so they can get a few bucks extra. Or eBay but that’ll cost you extra. The good news is that they’re nothing special, just regular small appliance cords. Just make sure to get the right end, snap a photo of the socket before your search. They can vary.
