Forbes's Mark Rogowsky takes the words out of my mouth:
"I buy from Amazon about three to fur times per month. I buy from them even if they don’t have the absolute best price because I know (a) the price is good and (b) if there’s a problem, they will take care of me. I’ve bought everything from a $2 item to a big-screen TV. With two-day shipping, any item I order by Wednesday will be at my home sooner than I’d typically have it from brick and mortar because—like many people—shopping is typically not done until the weekend."
