Yeah, it seems like this is where Shop Sections become our friends :)
I agree with Grimmie, it's nice to see a variety of things, and I like poking around shops that have different kinds of products. I figure, a department store website has a ton of different sections, right? Why not our Etsy shops!
I'm sure there are very valid reasons for setting up a separate shop though. Just can't think of any off the top of my head.
