No, Mushkin just had lower memory prices when he did it. They do not anymore and unless memory prices stop going up and start coming down, it will be some time before the $165 can happen.
As it stands, Mushkin gave me a quote of $169 + Shipping as a now authorized reseller. djohn is doing it again at $175 vs. my $173, and I am sure he is a authorized reseller also. The way I figure, he will walk away with a couple hundred in his pocket. Nothing wrong with that really as he saves people money.
With my price, there is a possability I can lose money, but that would only be a trivial cost compared to the money I save doing a group buy.
Anyway the choice is all yours, this either works or it dont.
