Payless' buy one, get one half-off sale is on now through May 3, 2010. I'm told everything is included in the sale, including shoes, sandals, boat shoes, hats, scarves, boots, and accessories. No coupon code is needed.
Before the discount, Gladiator sandals (are they still in style?) are $15-$25, and sandals and heels are $17 and up.
