MDSolarSciences' headline offer is 30% off your order, which applies sitewide and offers a strong saving across any basket size. This deep discount beats everything else available right now, though you should compare it against other active deals to see which delivers the biggest value in your specific situation.
Shopping your first order: If you're a first-time customer, the 20% off first order deal is automatically available to you. The 30% off offer saves significantly more, so grab that instead—it will cut a larger amount from your total regardless of what you're buying.
Small baskets under $75: The 30% off promotion remains your best bet here. Free shipping on all orders is also available, but the percentage discount will save you substantially more than the shipping benefit alone.
Orders of $75 or more: Again, 30% off outperforms every other option. While free shipping on orders over $75 would eliminate shipping costs, the percentage discount will dwarf that saving. For example, a $100 order saves $30 with the main deal versus around $7 to $10 in typical shipping charges.
Buying bundles: If you're shopping from the selected bundles, check whether a specific bundle qualifies for the 25% off bundles deal. On qualifying bundles, compare this against the 30% off sitewide promotion—the 30% will usually win, but on smaller bundles the 25% might be closer. Run the numbers in your basket to be sure.
Sale items and skincare under $152: The skincare products under $152 section and any sale merchandise still qualify for the 30% off offer. Use the headline discount on these items rather than shopping them separately.
Newsletter signup option: If you haven't shopped with MDSolarSciences before and want to stay updated on future deals, you can sign up to the newsletter for access to special offers—but the 30% off sitewide promotion is available right now without signup, so there's no reason to delay and miss out on the current deep discount.
At checkout, only one offer applies, so compare your calculated total under each available deal and select whichever produces the lowest final price. The 30% off promotion will almost certainly be that choice, but it's always worth double-checking, especially on bundle purchases where a targeted bundle discount might occasionally edge ahead.
