Holy mother of all hotness - Amazon has been absolutely killing it in the mobile deals lately, already firmly capturing our Deal of the Week spot with the sweet $174.99 HTC Thunderbolt deal.

Update 5/10/11: The deal is back for a limited time again! Judging by the last promotion, this one will expire sometime before May 15th.

Forget that - the new 9.99 Thunderbolt deal that just went live on Amazon Wireless is the lowest recorded for this phone to date, making the price of the first 4G LTE Verizon handset almost half of what you would pay at Verizon ($250). Not bad at all, eh?

The offer is available to new individual and family accounts and will run through the end of April 25th, so you only have a few days to deliberate. At $199.99, upgrades for existing customers are not as hot but still offer a cool $50 discount compared to MSRP.

As always, free 2-day shipping awaits, so hurry up and pick yourself up a speed demon or 2 before Amazon runs out of stock.
