butter LONDON's hero offer is 40% Off Lip Collection, which gives lacquer lovers a strong discount on the brand's signature lip shades. That said, butter LONDON has a deep roster of overlapping deals, so the best choice depends on what you're buying and how much you're spending.
For small orders under $50: If you're picking up just a nail polish or two, the 25% Off Sitewide deal will likely serve you best. For a single product that falls into the discounted categories, 40% Off Lip Collection beats everything else if you're choosing a lip shade, but the 35% Off Makeup Products deal comes close on other cosmetics. Newsletter signup is also worth considering if you're a first time customer and want access to special future offers.
For orders between $50 and $100: This is where the August Sale Free Gift offer becomes relevant. If you're spending over $50, you'll get a free Patent Shine 10X Nail Lacquer in Garden Party added to your order, which provides genuine added value alongside percentage discounts. Compare this against the 25% Off Sitewide deal to see which saves more in your basket. The 30% Off Your Bundle + Free Bag on orders with 3 or more nail treatments is also strong if you're buying multiple polishes and want the complimentary bag.
For larger orders over $100: The tiered product discounts start to pull ahead. If you're buying 4 or more selected products, you unlock 35% Off, rising to 40% Off at 6 selected items and 45% Off at 9. The same tiered structure applies to bundles, with 24% Off for 4 bundles, 35% Off for 6, and 45% Off for 9. Calculate which threshold you'll hit and compare the resulting percentage against the flat 25% Off Sitewide. The 50% Off Selected Products from the Last Chance Sale can beat everything if the items you want are included, so check whether your picks have that label.
Only one offer applies at checkout, so add your items to the basket and compare the savings each deal would generate. The biggest percentage win in your specific cart is the one to claim.
