Here is what I will never pay full price on:
Clothes at department stores (Macy's, Lane Bryant, etc)
Name brand packaged snacks
Why? Because you shop and buy ONLY when they are on sale! That being said, I purchased these shoes today for $59.97, discounted from $99.99 (that is a $40 difference!)
What a great deal, huh? Ok, I know they are a little loud, but they were the second to last pair of 9-1/2s that the store had in stock. We even called to another sports store down the road to see if they had the kind I REALLY wanted (Asics GT-2130) but were told they were sold out there as well.
It's amazing how quickly my old shoes broke down. I bought them about 6 months ago, and comparing to the shoes I bought today, there is a huge difference in cushion and support.
So, moral of the story today - REPLACE YOUR SHOES EVERY 6 MONTHS IF YOU WEAR THEM REGULARLY OR WORK OUT IN THEM! But only if they're on sale.
