I've worked as an editor at WaveDeals since 2019: I publish and keep content up to date, including this “SEALIGHT” page. Before a code goes live I check the terms of each offer — which shopping categories it applies to and whether any items are excluded — and I update the page promptly whenever something changes. In my experience, the biggest savings at SEALIGHT usually come from limited-time brand sales and sitewide promo codes applied at checkout. Keep in mind that offer terms can change on the retailer's side, and some codes may depend on your delivery region.
