After seeing how many people keep s**t stored in 10 year old random cardboard boxes in their garage or laundry room, I am gonna say storage tubs. They are hardly expensive, uniform in size, stack well, and aren’t going to deteriorate if they get a bit wet.
A good and comfortable chair to your desk. Especially when you plan to sit there a lot for studying or if your job requires you to sit. It will spare you a lot of back pain.
Bread from a bakery instead of regular stuff on the grocery store shelf, particularly if you can get it still warm from the oven, or at least very fresh.
A good “under sink” home tool kit if you dont have one already. I can say as a newly married 20 something it was the most useful gift my father in law got me.
As a home owner, I can’t say it enough. A wet/dry vacuum.
Ten foot charger for your phone.
Professionnal photographer at your wedding. Food, music and so on are nice but goddamnit don’t cheap out on the photographer.
Those pictures are everything you’ll have from your wedding for the rest of your life.
A toothbrush. It is literally life saving and can prevent you a whole world of pain in both your body and wallet. Bonus points if you brush twice and day and floss.
