Should I Buy the following and piss off the wife??

Buy them! I was buying and selling parts before i met her, stopped after we were together to please her, problem was she always seemed to find a reason to be pissed at me. So I would resent her for it, now i dont care if she's gets mad or not. A side note, this is assuming you have an income, job or retired. Goverment assistance, then you need to use that extra money to get a job.
