I lucked up into an end of season sale at a locally owned outfitter's store this spring and got 3 pairs of Toms @ $15 each, but they were all winter Toms, lined with flannel. For my new black Toms for the summer, I had to pay the normal $45 bucks. (Still, I'm all set for the Fall!)
Every time I go to Whole Foods now, I duck in (they're next door) but so far, lightening hasn't struck twice!
I think you're probably just going to have pony up and pay retail, sad to say, unless you just really, really hit it lucky.
