MASKC's headline offer is the up to 90% off summer closing sale code, which delivers the steepest discount available and works on website orders. This is your go-to option if you're shopping during the sale period and want maximum savings on eligible items.
Shopping during the summer closing sale? The featured up to 90% off code is your best bet. If you want an extra boost on top of sale prices, check whether the extra 30% off sale styles code works with your cart—it's designed for select sale items and could pile on even more savings if the items qualify.
Buying full-price or non-sale items? The 20% off codes (the flash sale, sitewide, or standard purchase options) all deliver the same discount level at 20% off your order. Pick whichever code is currently active—the terms state they cannot be combined, so you'll use just one at checkout.
Not sure which code to redeem? Head to the product pages you're interested in. If items are marked as eligible for the sale discount, the up to 90% off code will give you the largest saving. Items clearly marked as part of the summer closing sale will likely qualify. For everything else—full-price masks and non-sale styles—stick with one of the 20% off codes for a solid baseline discount.
Browsing without a code in mind? The sitewide up to 80% off sale (no code needed) is also running and catches items eligible for deep discounts across the entire site. Compare what the code-free sale shows in your basket against the code options before you check out; items will be clearly marked with their eligible discount level on the product pages.
Signing up for a subscription? A 50% off first subscription order deal is available if you want to set up automatic deliveries, though this only applies to your first subscription purchase.
Only one offer applies at checkout, so take a moment to add your items to your cart and see which option produces the bigger saving. The 90% off code will typically win for summer sale items, the extra 30% code for select sale styles, and the 20% options for everything else. Compare the final totals and grab whichever saves you the most.
