Yes, I remember that rush too -- at least when I started intentionally buying them rather than an accidental purchase!

I guess some things change (at least for some of us) as we get older. When I bought a pack of US Polo Assn string bikini briefs in person in Walmart a few weeks ago I was already back out to my car before I realized I'd been rolling all over the store with them in plain view in the shopping cart. <SHRUG> I don't know if I'd have done that 30 years ago as a teenager!
But for sure I would have as I got just a bit older, as I have always had some in-store purchases to go along with the online ones, even as I was getting the majority of my underwear from Prevail but even moreso with Kiniki. And K-Mart for sure, back in HS all the way through to almost the very end. Joe Boxer lost me in their last iterations of their string bikinis and thongs, but 15-20 years ago, they'd have been in the (actual, physical) shopping cart routinely!
