When Do You Say, "I Won't Pay That Much"

I just saw a mascara listed for $70. Holy crap!  Who would pay that much for mascara?  That is just plain crazy.  It did get me thinking, what is the limit that you would say, "That is way too much?"  What would you pay a lot for?  


I think I'm a pretty frugal person.  I hate paying retail for anything.  I bargain shop, check ads, go online and compare prices.  If I really want something, I try and find a good deal for it.  But, there have been occasions that I paid more than normal for a product.  


What is too much?  I guess it really depends on what the item is.  It also depends on whether that item is really needed or if it's just a want.  I'm sure there are a lot of things that I have, that I may have only paid $5, for, but since I didn't really need them, you could say I overpaid.  


It really makes me think. I have probably overpaid for more things that I even realized.  At least I can say I never paid $70, for some mascara.
