There are two ongoing promos through the rest of the season (lasting until Dec. 31):
Spend $125 and get a free pair of studs (chosen at random)
Spend $500 cumulatively throughout the season and get $100 in credit to spend on another order.
And as always, C+I has free shipping on orders over $100. The shipping isn't bad on smaller orders either, though- $5.95 flat rate.
Please let me know if you have any questions about the jewelry! I have a kit of it and I can do photos or videos if I have the item.
