4Wheel Allignment, or Camber Kit?

Hi there, you guys, i just was wondering what would be the difference between the two.
I went to a shop and he said that he could get all my wheels alligned for $51.50....so what is the difference in that and spending $150+ on a camber kit? Doesn't the allignment fix everything?
Any comments would be appreciated

The camber kit allows to you to adjust the camber farther than your car can without it. You will want to do a 4-wheel alignment even after you install a camber kit.

An alignment is the finishing touch that is almost required when you make any suspension adjustment just to be sure everything is straight and you get maximum tire life for your setup. Also an alignment can only fix so much camber, and if it's more than like 1 degree off, usually a shop can't do anything about it, and you'll have to get a camber kit anyways to fix it if you choose to do so.
