Again, cardio. It's called Flash for a reason so you have to be quick and understand that it's more of a competition. You get so excited when you get an email about an online flash sale or an invitation to an after hours store sale. You will scrap all of your plans so that you're able to attend alone - you don't want to tell your friends about it because they might end up buying something that you wanted; it's best to eliminate as much competition as possible.
