Costco and AT&T have teamed up – finally – and are offering free activation and a free accessory kit. The Costco membership is worth $45 so this deal is totally worth it since AT&T charges $35 for activation alone. Factor in the free Bluetooth headset, car charger and case and you’re well into the black. To get there go to Costco.com and you’ll then be redirected to a co-branded version of AT&T’s website. You’ll have to enter your membership ID to gain access. The best deal looks to be on the Blackberry Curve 8310, which not only includes the above, but is $50 cheaper then the regular new customer price ($149.99 vs $199.99).
