once again I can't take credit.
@The Loafter found the original deals on those drivers, and
@babybud had grabbed some too. I just posted them again when I saw them drop even more.
also fwiw I did call Arrow to find out about warranties they said I have to contact the mfg directly on that. I also asked how the pricing worked and how was it possible to be getting stuff so cheap. they said its all automated and compares competitors pricing and a bunch of other metrics. it runs every 10 minutes so if you see a deal, you are only guaranteed that price based on when u add it to your shopping cart. if the price changes before you check out, and you change quantity it will update your cart to the new price. something to keep in mind. also they do price matching so if you find something cheaper on Digikey screenshot it and then buy on Arrow to get the free shipping.
