Life hackers, how do you buy your underwear?

I possess few life hacks, but when it comes to underwear, I buy underwear from Costco. It is a great life hack. Costco underwear is of higher quality than any namebrand underwear I’ve ever purchased at department stores. It is more comfortable. It lasts longer. And it is much, much cheaper. <br><br>I buy an 8-pack of unadorned waistless “boy shorts” for $12, and each pair is better and cheaper than anything I have bought at Nordstroms or Macy’s. <br><br>What is your underwear hack? Do you buy them in bulk? Do you have a super expensive brand that you swear by? Do you go commando?
