Long a popular gift option, “of the month” clubs — in which you sign up and pay a fee to have goods like coffee or wine sent to you every month –- have recently caught on among the fashion set. Shoppers can now opt in to recurring shipments of everything from beauty products to jewelry to shoes.

Lunar Blue necklace and Desert Sand earrings, both JewelMint.

One example is the four-month-old website JewelMint. The brainchild of celebrity stylist and designer Cher Coulter and actress Kate Bosworth,  the site offers members a new batch of exclusive, limited-edition jewelry, sent to them each month. Each piece is just $29.99.

Or sign up for Birchbox, which launched last September, and for $10 a month you’ll receive a box filled with beauty samples from in-demand brands like Korres and Stila picked out by the site’s editors, two Harvard Business School grads. If you find something you like, you can purchase it through the site.

Last Monday, Sole Society launched to cover the “shoe-of-the-month” category. Created by the people behind flash sale site Hautelook.com, it operates much like JewelMint — members can pick out a pair of shoes each month for a fee of $49.95.

In return for your loyalty (and money), each one of these sites promises access to a curated selection of great products, many of which aren’t available to the public. Both Sole Society and JewelMint make potential customers click through a style quiz; offerings are then tailored for your individual preferences. In the competitive world of e-commerce, there’s a definite advantage here — shoppers have to return to your site at least once a month to browse and/or buy. Still, the challenge is getting people to sign up in the first place — and renew their membership once they do.
