Limited Edition Boxes are my favorite items to purchase from Birchbox. These are a mixture of full and sample sized items that usually fit a specific box theme. All boxes have a value far greater than the cost so they are a great deal when the items you want to keep exceed the value of what you’re paying. Better boxes sell out quickly, but the ones that linger will occasionally pop up in the sale section for 30% off. Aces sometimes get 40% off on sale items. Predicting which ones will sell out is not always easy so I buy the ones I really want close to the release date. If you’re on the fence because of price, wait it out.
