Same. We go away, or have dinner somewhere nice, enjoy each other's company. There's just no point with presents - if either one of us wants something, we already got it for ourselves. I think it's lovely that some couples have special talents to make or craft things for each other but we're not those people.
Makes sense, we tend to mostly focus on consumables (usually food or drinks) for presents, even someone who has everything will still enjoy some chocolate
Probably every other time either of us are in the grocery store. Might be flowers for either of us, might be a food the other likes, might be something odd to try together.
Can't afford much currently, so I try and make special food. Recently it was vanilla ice cream with maraschino cherries mixed in. He's been enjoying it! Holidays or birthdays I'll make tiramisu with homemade ladyfingers.
