Amazon has now price matched your Newegg link so the original link shows the same 99.99 on Amazon now.
Now sold out at both Newegg and Amazon.
Newegg still shows in stock when I click on the link just like the Amazon link. However Amazon is now 119.99 and only 15 left and not sure if Newegg's is higher price now as well or not. Wonder if the listing on Newegg is wrong never tried to add it to a cart and apply the promo code. Amazon's definately increased their price. OK I see it is from Tiger direct now not amazon. Hopefully the Newegg link is still valid.
When I clicked on the Newegg link yesterday it showed "Sold Out", but it's back in stock now. Maybe they got another shipment in.
With Amazon, they allow other companies to sell under the same product listing (and apparently to have the same product under many other listings), so when they sell out or another company's price is lower that will be shown as the seller rather than Amazon.
However, Amazon will still be listed under "More buying choices" and you used to be able to select Amazon and get the lower price when they were sold out if you were willing to wait (usually 1 to 2 weeks), but that wasn't the case when I checked yesterday.
It's also back in stock now at Amazon, I see.
