Another example of why I am a geek.

Pee Wee: 'Hi. I was calling to see if you sell lightbulbs'.

Store Rep: 'Yep. We sure do. Any specific type?'.

Pee Wee: 'MR16's, with a GU10 base'.

Store Rep: 'Sure do.'

Pee Wee: 'Yippee! Cool. How much are they?'.

Store Rep: '$7.49 each'.

Pee Wee: 'Ouch. They normally retail for around $4. Ok. Thanks!'

[Thinking to myself, I just found a website that sells them for $2].
