*UPDATE* – Just caught that it says the deal ended yesterday. Who knows, maybe Costco will still let it go for $99 if you go today.

If you are in the market for a brand new BlackBerry Bold 9900 on T-mobile’s 4G HSPA+ network, you can now buy one for only $99. That is of course on a new 2 year contract or $129.99 with an eligible upgrade.  The catch? You have to be a member of the retail giant Costco. Compared to the $249.99 sticker price T-Mobile charges, this is a steal!

Also, Costco waives the $35 activation fee and an “accessory bundle”. Go get yours and enjoy the best that BlackBerry has to offer. This deal also looks to be in-store only, as the 9900 is still listed at $149.99 on Costco.com.
