How to Shop in A Sale??

Hola Lovelies!!
Ok so its officially the Sale Season!!! I get messages almost everyday from all leading brands Pantaloons, Shoppers Stop, Max, Westside etc etc that they have this on sale, that on sale !!Upto 50%, upto 60% and what not!!And guess what I have a few friends abroad, even they told me how it was the sale season there!! So I have to confess I went all out this sale season and " Shop till you Drop" was the only motto working on my mind. I got the best shoes, dresses, make up, more dresses, more make up and finally when the week ended I knew, I had so much to share!!!So here is a list of to do's when you plan to go shopping in a sale!!
