I make an effort to be a savvy shopper, and websites like this one help out. For instance, there is a particular brand of tights that I like, and when I buy them in the store, they're about $7 a pair. Pretty fucking outrageous when you consider they'll have holes by the time I wear them three times. So, I go online to buy them at $17/4 pairs. Much better, although I do have to take into account the shipping fees -- except I go to the coupon website I linked to above, and find a coupon that gives me free shipping, saving me 7 bucks.

I love a good deal.
