My wife is fine with my spending and i often get stuff delivered to her work because
a) she works in the small office that receives the post so can keep and eye on it and
b) drives to work so it’s easy for her to chuck it in the car to bring it home rather than me bring it home on the bike or the train
However I do use a pseudonym on my orders (and other online sites) that I created many years ago to avoid having my personal details bandied about on the internet too much. It’s a faintly amusing name and this always makes the ‘girls’ in her office laugh. They even know it themselves now and will take post in for my alter ego when my wife isn’t there!
