And of course, buying in bulk is a great savings. I love to go to bead shows because I can buy chain by the foot, beads on 12"-16" strands, silver charms, toggles, crystal, pressed glass and a million other items for a fraction of the cost of retail. Bead shows are also a great place for networking, meeting the artists who make what you love and working out ways to help each other by promoting each others work!
Another little secret - trolling the internet sites for the best deals is worth your time too! Sometimes when an artist is just getting started their work will be priced at a discount while they try to build a customer base, an artist might be having a clearance sale or maybe they're trying a new type of material and testing the market. Stick with artists you love, its good to build relationship, promote each others work!
