Amazon ran a big sale in early January 2013 on PI shorts/bibs last year. I scored those PI attack shorts for $32 (list $80) so I've been patiently waiting all year figuring they'd run the same sale this year. I've been checking prices every day or two since the new year. Don't wait very long to pull the trigger, last year the sale disappeared within a few days (or I would've bought two more pair of shorts.) Even as recently as last week the Pro shorts were still $175 in my size (M.) January is generally a good time to stock up on summer cycling clothing if you can be patient.

Edit just went for a ride with my new Pearl Izumi Elite bib shorts (still waiting on the Pros to arrive.) The chamois is SO MUCH more comfortable than my PI attack shorts. My saddle felt a lot better at the end of the ride as well.
