What’s everyone’s secret when searching for good deals on OEM through eBay or Mercari? I always get 3rd party bands no matter what I type. Even when I filter the brand as Apple.
There are ways that sellers of 3rd party bands can create their listing so that it purposely shows up on searches for OEM bands. In turn, there are sellers of OEM bands that don't do a great job in ensuring their OEM bands come up on OEM band searches. I typically search for Genuine (or OEM) Apple Watch bands, but exclude the word "leather", since genuine leather 3rd party bands will show up. You need to have patience searching for OEM bands on eBay.
