Pauper's Bounty, which sells sterling silver jewelry for under $20 (www.paupersbounty.com) has a promo where you get free shipping for orders over $40 during May. But you can combine two codes to get a better deal:

Facebook code: MAYFLOWER gives you a free gift with the purchase of anything that has a flower on it

Ourcreativeworld blogspot code: CWJUNFREESHIPPING gives you free shipping on any order over $20

So basically, if you spend $20, you get free shipping, and if one of your items has a flower on it, you get a free gift too. Somthing to think about if you need to buy gifts or update your jewelry collection for the summer...I've gotten free gifts from Pauper's Bounty before and it's always sterling silver (one pendant--spent $8, one pair of earrings--spent $27).
