As much as I love festive lights, Christmas music, and the smell of pine trees, my favorite part of the holiday season is decorating the tree with the mishmash of ornaments I’ve collected over the years. If you’re looking to build your own collection — or find the perfect gift for a loved one to hang — now’s the time to enjoy great prices on Hallmark ornaments during Amazon’s Cyber Monday sale.

I’m currently eyeing the Piplup ornament ($9), since they’re my favorite Pokémon Brilliant Diamond and Shining Pearl starter, and I already know the exact coworker I’d gift this ornament of Samus from Metroid ($17). I actually did gift this sledding Snoopy ornament ($8) to my husband last year and I cannot recommend it enough; it’s just that cute.

There are a ton of other great and geeky options below, including ornaments for Star Wars, Animal Crossing, and anime fans.
