Bought a fleece sheet set for my fiancee, cuz that's something she's wanted for ages cuz she likes being super warm while in bed.
And then also one of those "Night Sky" posters that shows how the stars would be generally be positioned on any particular date. I opted for our wedding day next year, and she loved it. Had to give up the frame that held one of my Bloodborne lithographs for it so we could hang it ASAP
And some other stuff as well, she decided back in January she wanted to start a web
blog, so me paying for hosting and the domain and running the majority of the admin stuff is another gift as well.
We already celebrated on Saturday/Sunday, since we were snowed in anyways. She got me a personalized wallet, since my 10+ year old one has basically been barely held together for the past year or so now and then back in January she also bought me the rest of the Witcher series books I needed. All in all a pretty great Valentines this year.
