Cudoo's 20% Off Sitewide deal is the top offer on the page and works well if you're shopping across different courses or categories. That said, the brand regularly runs deeper discounts on specific language courses, so your best savings will depend on what you're learning and your total basket size.
Shopping for a single language course: Check whether Cudoo currently has a specialized course sale running on what you want to take. The Huge Sale on the Complete American Sign Language Online Course goes down to 83% off, and the Complete Accredited TEFL Certification Online Course hits 80% off, while Japanese Language Courses reach 83% off. These beat the 20% sitewide deal by a huge margin if the course you need is on sale. If your course isn't part of a featured promotion, the 20% Off Sitewide offer is your next best option.
Shopping for multiple courses in one basket: The 20% Off Sitewide deal applies to everything you add, making it straightforward if you're buying several different courses. Compare it against any single course deals that might apply to items in your basket, since a deep discount on one course could combine better than 20% off your entire order. The 10% Off All Courses and 5% Off Your Courses options offer smaller savings than the 20% sitewide, so skip these if the bigger discount is available.
For courses not currently on sale: Reach for the 20% Off Sitewide offer or consider signing up to Cudoo's newsletter using the signup link at the top of the page if you're a first time customer, as the brand notes it runs special offers and promotions for subscribers. The Up to 80% Off Courses deal sits on the page too, though it's unclear which courses qualify, so test it against the other options when you're at checkout.
Only one offer applies at checkout, so as you're building your order, compare what the 20% sitewide would save you against any applicable course specific sales. Take whichever produces the bigger discount on your total.
