Sierra Nevada Pale Ale Price Check

I am a complete newbie to beer. There was a local grocery store selling a 12 pack of Sierra Nevada Pale Ale bottles for $11. The special ends wednesday. I have a twele pack of another brew in the fridge but I was wondering if this is a good enough price to jump on it or is it about normal? I apologize if this is a stupid question but I honestly don't know what this stuff goes for. Thanks fellas.
