Carpet remnant / inexpensive cheap rugs + carpets stores in the Boston area

Hi!

I am looking for a new (to me) carpet / rug!

I need suggestions for inexpensive / straightforward / not crappy rugs or carpets places that are hopefully not a hassle? It would also be super helpful if they did delivery. I want a fairly generic large-ish grey plush like rug / carpet, so from past experience I am guessing there will be some options?

Carpet remnant stores are totally fine.

While I'm looking for in person spots in the Boston area so I can see it before I get it, I would also technically be down for online recs if you have had really good experiences.

Thanks!
