Subscription boxes are curated packages of products that are delivered to subscribers on a regular basis, typically monthly. These boxes often focus on specific themes or interests, such as beauty, fitness, food, or books. Subscribers pay a fee to receive a selection of items, which can include samples, full-sized products, or exclusive items not available in stores. The appeal of subscription boxes lies in the element of surprise and discovery. Each month, subscribers can look forward to receiving new and exciting products tailored to their preferences. Popular examples of subscription boxes include Birchbox for beauty products and Blue Apron for meal kits.
