A lesson in smart buys for guys (pardon my rhyme, I need to improve Mondays in any way possible), these $15 t-shirts are an absolute must for Prime Day. Rich owns a few, and I’ve even been known to buy one (or 25) for myself. Too many t-shirts isn’t a thing. They’re worn constantly, and as such, they have a tendency to need refreshing every now and then. Pre-empt that horrifying moment when you look in a drawer and realize all of the t-shirts in your home would be better off used as dish rags, and scoop up a few fresh tees.
