Replying to Quick waxing question

Theres like 50 threads on this but they all ask a different question.

2 quick ones,
1) why the hell do vises cost so much. you can get a vise for like $5 at home depot, at least thats what I think. there's vises online for like $129, how the hell do you spend anywhere past $20 to produce a vise.

2) this being the serious one. how the hell do i hold my brakes down while waxing. i must be dumb for asking since there's prolly some easy way apart from taping them or something. or do these $129 vises have this feature which obviously costs so much
