The main offer at Vitruvi is the 20% off all orders voucher at the top of this page, a checkout code that takes 20% off your entire cart and cannot be used with any other offer. That code is best when you want a straightforward percent reduction across everything in your order. Several automatic sale and free gift deals can beat it for sale items or larger orders, so weigh those options for bigger carts.
Big carts over $175: If your order tops $175, you get a free Push Diffuser automatically at checkout. That free product may be worth more than 20% off part of your basket, especially if you were buying higher priced items, so compare the dollar value of the free diffuser to the 20% saving on your total. Also note a free Drive Diffuser is available automatically on orders over $150, though that deal is valid on sale products only, so it helps mostly when buying marked down items.
Orders between $80 and $175: Spend over $80 and free delivery applies automatically. On a $100 order, for example, the 20% off voucher at the top of this page saves $20, taking the total from $100 to $80. If your normal shipping would be $10 to $15, free delivery could beat the voucher, so compare the voucher final price to the order price with automatic free shipping. Use whichever yields the lower final total.
Mid sized carts under $150 but above typical shipping: If you expect shipping charges and your subtotal is under $80, the 20% off voucher usually wins because it reduces the product total directly. On a $120 order, the 20% off voucher saves $24, taking the total to $96. That is often better than smaller automatic discounts or the 10% signup deals.
Buying sale items or bundles: Many sale items are already reduced, with up to 75% off select items, up to 50% off blend kits and diffuser bundles, and up to 42% off selected bundles. Sale prices are applied automatically and the 20% code cannot be used with other offers, so if an item is marked 50% off from $100 to $50, the sale price of $50 is cheaper than using the 20% voucher on the original price, which would be $80. In short, prefer the automatic sale price on marked items unless the 20% code applied to non sale items still gives a lower total.
First time customers: You can sign up for the newsletter to get 10% off your first order. That 10% is smaller than the 20% voucher, so the 20% voucher is generally the better first order saving, unless you need a code that specifically applies to a restricted item type or a sale item that the voucher cannot touch.
When deciding, calculate the final price for the same cart under the 20% voucher and under any automatic sale, free shipping or free product deals that apply. Pick the option that leaves the lower total. Only follow combination rules that the offer terms state; most of these offers are applied automatically and the 20% code cannot be stacked with other offers.
