It's 2020 and I'm still buying stuff from the sims 3 store

As an owner of the store, I can say there are a lot of really great items there. If you like dressing your Sims, one thing I would recommend getting are all of the clothing and hair items which didn't come as part of a set (just sort the catalog by 'oldest to newest' and they'll show up first). There are some really fabulous items there (especially for the YA Female).
