As far as subscription boxes go Luxe Box is fantastic. Delivered quarterly.

Cost is: $26/quarterly, shipping included

You receive 7-8 trial-sized products.

I look at the different size descriptions as follows:

Sample size: Good for 1-2 applications
Trial size: Good for at minimum 10 applications
Full size: Good for a lot more applications than trial

Every box delivers as promised and often has at minimum 1 full sized product.
