shit if you guys just got tog then something small like gift card or just dinner.
im single this year so nothing. but if i was still with her prob a charm from tiffanys ($100) for her bracelet from last year and some shoes and prob some small shit she likes (some puzzle or book, hangers or random shit like that). i gave her like one of them 24 packs of hot cheetos from costco last year cause that was like her diet, all she ate. but small shit like that sometimes end up being the better present.
if you cant spend couple bills on your girl, then you shouldnt be worrying about presents. you should worry about getting your life in order.
