Coterie has UV gel polish sets – for $90 you can get bonder, top and base coat, a UV light, and pick 2 polish colors. If you need a simpler kit, you can get 3 colors for $33, or 3 colors with bonder or base and top coat for $44.
Sneekpeeq has Haute gel polishes for $13. While this is a bit high, if you are a new customer, I believe you get a $10 badge right away, and if you use their iPad app they will give you a free shipping badge. I did something similar on the Layla polishes and was able to get 2 for $5 each with free shipping. Not such a great deal though without extra badges; I find their shipping high, especially on a small item like polish.
