Check out wanelo.com! You can "save" your item there. It is like pinterest but instead of people looking for ideas to gank, people go to Wanelo.com to look for things to buy.
Twitter is a REALLY good resource if you really interact with people on there. Google+ is on the rise. Craft shows and expos are GREAT ways to promote your business. Consider buying ad space on blogs of relevant content. Leave business cards are local coffee shops, ice cream shoppes, stores, parks, community center bulletin boards. Put fliers with a promo code on your neighbors doors or cars at the mall.
