My wife caught me too. Felt like I was caught with another woman!
You need to setup an infidelity account where you can place your money for after market part addiction fixes.
Next, arrange shipping to your business address.
Then plan for routine bike maintenance to be performed at the dealer where you dropped off the parts the day before.
IF your wife notices that the bike has changed, mine rarely does, say "Some guy bought all of these parts, and his wife freaked out, so he sold them all to me for practically nothing to get her off of his back." Win, win.
