Yes, I do. I advertise with a popular blog and have been for about a year. I am very happy with it. Along with a side bar ad, I do giveaways, sponsor charity events, and she sometimes includes me in articles. She also did a feature (free) to start which has brought me close to 1,000 sales to date. I direct the ad to my stand alone site, not to Etsy, but she has linked my Etsy shop before so I get traffic on both!
