It really depends on the products inside! 🤔 For me, I will take a careful look at the sets and find reviews on each product and see if they are suitable for my needs. I will then consider if its cheaper to buy it as a bundle, or standalone products. I'm assuming you are looking at brand boxes sold on brand websites / online retailers like Wishtrend / Stylevana etc etc?? If you are referring to those boxes on recurring subscription, I'm not familiar with them...
