Ski boots can easily set one back $500. How much should one spend on this necessary item when skiing? You could just rent them for a day if you don't ski much. But if you ski a lot you are better off owning a pair. I've learned that you can find good deals on ski equipment if you shop around at multiple sporting good stores and look at their clearance items. I was lucky and found a new pair of ski boots for $19.97 (plus tax). They were last years model and would have been about $300 brand new. Post any good ski boots that you like in this section.
