It really depends what you're looking to buy. They have certain types of sales and it really depends what you're getting what the best deal is. For example, three of their best sales are:
- Buy 3 Get 3 Free
- Buy 3 for $30
- Buy 5 items, your entire order is 50% off
The B3G3 is most effective when you're buying a lot of products that are the same price. The 3 for $30 sale is most effective for their priciest products, like some of the serums and skincare products in the $25-40 price range. The 50% off promotion is great for slightly cheaper products (such as skincare products in the $10-20 range), or for 1 or 2 pricier products and then 3-4 small travel-size products and hand washes and such. Basically, my rule of thumb is to never spend more than either 50% off the sticker price or $10, whichever is less, depending on the product. If you wait long enough for the right sale, you can always get it for under $10.
