Pre-shopping vs. window shopping

Do any of you pre-shop instead of window shop? OK maybe I should explain the difference.
Think about it this way: window shopping is when one drools in front of all the wonderful things seen in display windows. technically you aren't even really walking into the stores but rather DYING over the things you wish to have. I've seen people almost going into cardiac arrest!!!!!!!! No seriously sometimes you just cannot resist and the window shopping turns into actual shopping because temptation has devilishly taken over your mind!
Pre-shopping is what I have learned to do over the years.... YES years. Pre-shopping has three steps:
1. THINK about what it is you are looking for
2. SEARCH the internet for the perfect item(s)
3. GO to the store, try it on, see what it looks like in real life.
This process has helped me decide on what was worth buying and what was worth waiting for or even forgetting about.
Do you REALLY need these amazing leopard-print booties? In theory yes of course; your collection of shoes needs to be updated regularly. HOWEVER, maybe there is a better pair somewhere, and get this, with a discount.
Talk about CyberMonday... I am going NUTS here! SO many great deals!
Breathe...
Anyway, think about the concept of pre-shopping! You might get something out of it!
