When I was last in San Marcos, say at the beginning of March, I wandered through Prime Outlets - my favorite area being the north end by La Perla, Neiman Marcus Last Call, and Barneys - and there was a James Perse outlet that was being finished out.
You can't find a thing about it on the Perse website, but I promise you it's there and now open for business. And since JP tees and clothing never, ever go out of style, you're in for a bargain on classic, super-soft styles that you'll keep forever. It's on my list of must-stops when I'm in Austin next week. Perse at a discount? Yes, please.
