We get it. Maybe you're not the best at communicating your needs...no judgement (but maybe work on that?) If you need to show your wife that you spent less on your rig than you actually did, we're making it a bit easier for you.
Below is a link to a blank PDF invoice. Fill it out with your name, billing and shipping info, products you bought, and whatever price you want to show her for it all.
