But he is completely right, bricklink is the only place to get any amount of technic treads at a reasonable price. Unless you have to pay some import hefty on them, do look at other vendors that ship internationally, I got mine from Germany for cheaper than the UK vendors would do them for, even across the channel shipping was negligible.

You pull on your finger, then another finger, then your cigarette
The wall-to-wall is calling, it lingers, then you forget
Ohhh how how how, you're a rock n roll suicide"
