Now they're called Xfinity stores but before it was more of the warehouse for a distribution center. This was in South Florida.

I have one in my town. It's less of a store and more like a quartermaster? You go in to drop off hardware you're returning, pick up new hardware, ask for a replacement remote, pay your bill. It's mostly just to avoid having to send things through the mail and all the trouble that can be in some years and areas.

It will typically be one per Comcast service center. So if you are in a semi rural area, it might be in the bugger city the next county over, or there might be a handful scattered across a large metro area. They also serve as the rally point for all their cable guys.

I live in the Midwest and we have one in a strip mall. It’s basically like a mobile carrier store (AT&T, T-Mobile, etc). A few backless benches, a few service desks, a “sleek” counter, walls and large TVs lined with advertisements as well as some products (Xfinity/Comcast does mobile phone plans now too so they have phones, smart watches, etc for display). You can also return your equipment there but it’s mostly for signing up for services and billing help I suppose.
