I corrected your greeting. No need to thank me.
One of the first steps of being a member of the AR Addict Group is to remember that "3 is 2, 2 is 1 and1 is None." At this point you are not even up to the check out counter yet.
A tip that will help you getting to the important "2 is 1" step is to buy more than one part when ordering them. This is especially good idea when buying small parts like spring, detent pins, etc. as even when buying several of them the shipping often costs more.
Also it helps to keep in mind that small parts like springs can get easily lost. The best way to avoid having this happen is to use them to build more AR's before they get lost. Explaining to your wife the wisdom of not losing money by lost parts will make her realize what a financial genius you are.
I appreciate the correction. Thankfully I do not have an old lady on my hide about spending money... I just tell myself "Dang! You are so smart!" on all topics.
