Ha! Interesting question. I had a bunch of old briefs in tatters/shreds but have recently been making a lot of road trips and keep forgetting to pack underwear. So when I get to my destination I unpack in the hotel, say DAMN FORGOT MY F*CKING UNDERWEAR AGAIN, and go to the nearest Target and buy a pack of new ones - the cheapest multipack of briefs they have (no class here). I now have enough new underwear to last the rest of my life even if I remember to pack properly from now on.
OTOH, I've enjoyed checking out all the buff models on the packages.
