I don't think it's about indecisiveness: this shredder or that? I'm not cheap (look at my shelf of shoes if you don't believe that).
Today I bought 10 jars of a moisturizer I like that's being discontinued, and a Jawbone UP to track my activity levels, with the intention of stepping up my game by making myself accountable.
I hit "buy" and felt a sick moment, as if I'd just run over a baby. Then I was excited. No regret! Overbuyers Anon, here I come?
