Screenshot the payment-page total for a Brillare ritual kit, then rebuild the same routine as single products in your cart and buy whichever total is lower.
Before you buy a Complete Ritual kit from the Supersaver Bundles tab, price the same items one by one. A kit is not automatically cheaper than its products bought separately. Add the kit to your cart and note the total on the payment page, then swap it for the single products and compare.
Run the same check against the free-item offer. When Brillare runs a buy-more-get-one-free offer on single products such as Oil Shots, face serums and shampoos, the number of items you must buy to get one free changes between campaigns. Build your routine as singles inside that offer, see the cart total once the free item is applied, and put it next to the kit total.
Several kits come in both a Natural and a Professional version, each listed with its own price, so price both versions for your concern. The Ultimate Rosemary Hair Growth Kit holds two packs of Oil Shots where the Complete kit holds one, so compare what each total actually buys you, not just the discount label on the tile.
