I hope that cause it's National Poetry Month a lot of people buy a lot of poetry because I am friends with a lot of poets and I know they could really use the money.
No one buys poetry.
If you are curious about contemporary poets and small presses, The Lit Pub and HTMLGiant are good places to start looking at reviews of stuff you might not have heard of outside of a poetry class or MFA program. You can also bookmark everyday-genius or let people poems and check in on what they're doing, since there are new poets featured all the time. There are also TONS of online lit journals that offer some great stuff (from the past and currently published) --Ink Node, My Name is Mud, Lamination Colony, Paper Bag, and Noo Journal to name a few. And of course, if you want to take a more traditional route you can always download The Writer's Almanac podcast (or donate. They could use the money, too).
Though [almost] every poet I know has some kind of day job, whether it's teaching or working in a psych ward or working as a dom, I'd really love to live in a world where people bought poetry like the bought novels (and listen even that isn't asking for much like AT ALL). So think about purchasing some poetry, especially small press poetry this month. And, you know, rock on and etc.
