All Rshacks in like a 30 mile radius...sold out...
RS: Thank you for calling Radioshack on 123 Fake St. How can I help you?
Me: Hi, do you guys have the Xmods All Wheel Drive upgrade in stock?
RS (abruptly): No we don't.
or
Me: Hi, do you guys have the Xmods All Wheel...
RS: It's out of stock
or
Me: Hi, do you guys have the Xmods All Whell Drive upgrade in stock?
RS: You again, no we don't have it yet.
They don't even have to check lol, they all know whether it's in stock or not. I believe the Rshacks are in high demand for it because of my annoying calls

or maybe they want to torture me by not telling me that it's in stock.
