The thing I miss about university is that the bookstore had an excellent selection of pens that you could try in the store. But as I type that, I realize that I'm a scant few miles from a university.

Kinokuniya (the Japanese bookstore) usually has a pen section where you can sample pens/other writing utensils.

Thanks! I'll check them out. Any recommendations for pens?

I really like the uniball signo 207 for a smooth every day pen.

Hah. Sorry there's no guarantee that the pens in the article could be sold at that store.

JetPens have a number of sampler packs: https://www.jetpens.com/search?q=sample&v=2

As klyrs mentioned, university bookstores typically have a section for writing implements where one can try out pens. Additionally, every decent art supply store I've been in has had a section for pens with paper to try them out on. Art stores don't usually carry cheaper mass market office pens, but I do see some of the Staedtler, Pentel, and other pens recommended. I've even found pens I like that Jet Pens doesn't carry.

In the US, craft stores like Michael's and Hobby Lobby usually have a section for drawing that has a pretty good pen selection.
