I imagine the number depends on the size of the samples. Besides votive candles and tarts, you’ll receive bath and body products and there’s now a new baby care line as well.
On the other hand, if you want to become a contributor, it’s a good way to advertise your handmade candles or crafts. If you sign up for a month, you commit to sending in 20 samples. Of course the more you send in, the more people get to see your products. Also, if you send in 50 samples, you get a free sample box.
It sounds like a fun idea and a great way for smaller candle makers and crafters to get exposure. For more info see The Crafty Sampler.
