As the owner of Sparrow, Kirsten Coplans knows how hard it is for an independent, small -- no, minuscule -- business owner to build up clientele when there's little money for advertising. She and pal Melissa Santiago figured the myriad of boutiques around town were experiencing the same struggle. So they created Side Street Shopping List, a modest guide to fifteen local shops that help to keep Denver vibrant. Right now, the guide is distributed in stores -- with a coupon good at any of the participating locations included -- but Coplans hopes to someday expand to a website and instigate organized group events. Until then, she's a word-of-mouth expert.
