Thanks, Dan, Anna, and Stuart--it was right there, in tiny letters. So I wrote a lengthy review of my beloved SL-3, hit "Send," and they reminded me that I had to be logged in. I then did, but my password had expired and I had to set up a new one. My first review had been deleted, so this time they just got the Cliff's Notes version. But I got a 20% coupon.
And yeah, Stuart--thanks for the heads up on doing the coupon at the store. I live in Boulder, and I like to hit my bank on the mall, get my parking ticket validated, and slide next door to GoLite to pester the help. On your advice, I just now called my buddy at the GL checkout desk, and he confirmed what you said--the coupon is only good online. So I have to pay shipping and sales tax, but still...
Thanks to this thread for the 20% review coupon info!
