Interestingly enough all the futureshops that I’ve seen were converted into bestbuys by only changing the colour of the branding material from red to blue - everything else literally stayed the same
In my city they kept them as separate stores for quite a while, but in-store branding definitely changed colour. At one point, a Best Buy and Future Shop were actually sharing a parking lot. It was in a large "power center", with many stores between them, but still the same parking lot.
It took quite a while for Best Buy to finally rationalize its store locations and get rid of the redundancy. Some Future Shops took on Best Buy branding, and in cases like the one above one of them was picked to close.
In the shopping center close to where my parent lived there was a single store between the two. I remember it wasn't rare to see BestBuy labels in Futureshop too. They only closed the Futureshop once they merged them.
