Well IMHO it IS a different matter if we make a deal today for you to purchase my widget for $99, you "make" the purchase by ordering.
Then the sale price for the widgets I have in stock rises, so I CANCEL you and other customers existing orders, and start selling them to other folks for $299. Those folks you put on a list, you might have to buy from them in the current madness IF you NEED a widget, but when things return to normal they are not in your list of people you buy from.
The price of Pmags has not risen from the mfg to the distro, so if the prices triples between there and the home buyer somebody is cashing in. And the companies who do NOT (like Brownells) will go on my "good guy" list. Buying and selling is all free market, and so is choosing who we buy and sell to and from.
I bought a 45 acp pistol that holds 1/3 of a box of ammo in one magazine in 2007, the old ban had been out 2-3 years, I started buying magazines for it each time I went to Cabelas at $25 or so each. My wife naturally asked "why so many?" I showed her what similar full cap magazines sold for under the previous ban ($99 new in wrap) and her next question was "did you get all they had, can we get more someplace else ?". I stopped when I had 30 of them...sounds like a lot but if a new ban goes into place a fair trade would be 3-4 magazines for 1 LNIB pistol. I told other customers who were buying new high capacity magazines to buy 10-20 magazines and they all looked at me like I was NUTS.
