I know it seems like there’s a dozen of these invitation-only shopping sites, but here are a few more that caught my eye.

Shop It to Me

With one of the most customizable email formats among the invitation-only sites, Shop It to Me lets you select all the designers you’re interested in following and sends you an email digest of the best sales. Invite 10 friends to sign up for email, and you’ll receive a $10 gift card to the retailer of your choice. Designers vary widely: Urban Outfitters, White House Black Market, Ralph Lauren, Puma, Adidas and more.

One Kings Lane

Another invitation-only shopping site, One Kings Lane is for home decor and accessories. When you sign up, you’ll receive $15 credit free. There’s tons of really cute items under $15 that offer free shipping, so free stuff! Yay! For every friend you refer, both you and they will receive $15 credit on the site. This referral offer by far is the most generous I’ve seen of any of them, so I’d hurry before it changes. I just purchased the Built NY padded electronic cases–the olive laptop porter and the set of 2 portable hard drive cases for $50 shipped. Home goods spotted: Sigg water bottles, Vera Wang tabletop, Tourance baby blankets, Inked candles and more.
