Portobello Problem

I was at Portobello market today..did i buy anything except a muffin and frozen yogurt? No, why? Because i am TERRIBLE at deciding....i went in to 9374983274 shops and saw at least a thousand things i wanted, but everytime i saw something i wanted i thought to myself  "i'll probably find the same thing but cheaper if i look in a few other shops". That was my thought all the way through Portobello market and then i went back to the apartment....I feel ashamed...so to make up for this i might, for real, go back soon (it closes at 7) and just buy everything i see....i suck at buying things that isn't food...
