You didn't read the post did you? Miss Armadillo said "He's the son of one of our expert mechanics. He's probably been working on bikes longer than you have."

Having the expert mechanic's 14 year old son working on your bike is worth the $13.49 alone! She could've charged you even more!

On the other hand, a tube and some tire levers probably would've cost less.

Lets mark this experience down as lesson learned.
