Samsung is planning to open in-store shops in Best Buy retail locations. This means direct confrontation with Apple in Best Buy stores.
Samsung partners with Best Buy to bring Samsung Stores to 1,400 Best Buy retail locations. Apple has some in-store shops at Best Buy as well, but the focus is clearly on its own retail network.
To partner with Best Buy is definitely the lower cost option to create a bigger retail presence. Samsung offers everything from fridges to cellphones. It will be interesting if they put every Samsung product offered in a Best Buy in this new Samsung Experience shops.
