Monday Swimwear Promo Codes & Coupons September 2025

Monday Swimwear offers premium swimwear at premium prices, but our data-driven analysis reveals multiple strategies to secure significant discounts on their coveted pieces. SimplyCodes research has identified the most effective money-saving approaches based on historical discount patterns and community-verified tactics.

Time Your Purchase for End of Season Sales

Monday Swimwear offers its deepest discounts during End of Season sales in August and September. During these sales events, shoppers can expect discounts ranging from 20-40% off regular prices, with some items occasionally reaching 50% off or more.

Historical data analysis shows that Monday Swimwear's August/September End of Season sale consistently provides the best value. SimplyCodes tracking confirms these sales typically feature the widest selection of discounted items across multiple collections and sizes.

To maximize savings, add desired items to your wishlist before August and monitor for price drops. Setting calendar reminders for early August can help ensure you don't miss the initial markdown period when size availability is best.

Sign Up for the Newsletter for Immediate and Future Savings

Monday Swimwear offers a 10% discount on your first purchase when you subscribe to their email newsletter. This discount applies to full-priced merchandise and is delivered via email shortly after signup.

Newsletter subscribers receive early access to Monday Swimwear sales before they're announced to the general public. According to SimplyCodes shopping research, this early access window typically provides 24-48 hours of shopping before inventory becomes limited in popular sizes.

To maximize this strategy, sign up with your primary email and add Monday Swimwear to your safe senders list. This ensures you'll receive time-sensitive sale announcements without delay, giving you the best chance at securing popular styles in your size.

Check Sale & Clearance Sections Regularly

Monday Swimwear maintains a dedicated "Sale Resort Wear" section on their website with ongoing discounts throughout the year. SimplyCodes analysis shows this section is refreshed with new items approximately every 2-3 weeks, making regular checks worthwhile.

The brand occasionally creates hidden sale collections like the "40% Off Collection" that aren't prominently featured on the main navigation. These collections often contain limited-time offers on seasonal styles before they move to deeper discounts.

For best results, bookmark the Sale section and check it weekly, particularly on Mondays when new markdowns are typically applied. The SimplyCodes community has observed that Monday morning checks often reveal fresh inventory before it's promoted in marketing emails.

Leverage Single-Use Codes from SimplyCodes

Monday Swimwear has 152 single-use promo codes available through SimplyCodes at any given time. These exclusive codes provide discounts that aren't publicly advertised on the Monday Swimwear website.

SimplyCodes verification system confirms these single-use codes offer an average discount of 15-20% off regular prices. These codes can sometimes be combined with sale items for stackable savings, though exclusions may apply.

To access these codes, create a SimplyCodes account and search for Monday Swimwear in our database. Testing multiple codes during checkout can help identify the highest possible discount for your specific cart items.

Consider Competitor Codes for Similar Styles

Monday Swimwear has 1,510 competitor codes that may work on similar swimwear styles from other retailers. SimplyCodes data reveals these alternative options often feature comparable designs at lower price points.

Our analysis shows that competitor brands frequently offer more aggressive discount structures, with some providing up to 30% off for first-time customers. This approach is particularly valuable if you're flexible on brand but specific about style or fit requirements.

To explore these alternatives, browse the competitor codes section on SimplyCodes and compare similar styles before making a final purchase decision. This comparison shopping can yield substantial savings on nearly identical swimwear designs.

Qualify for Free Shipping

Monday Swimwear offers free standard shipping on all US orders over $200. This threshold is relatively easy to reach given their price points, with most full-price bikini sets ranging from $150-$200.

SimplyCodes shopping research confirms that combining multiple items in a single order to reach the free shipping threshold is more economical than placing separate orders. The standard shipping fee for orders under $200 typically ranges from $10-15 depending on location.

When planning your purchase, consider bundling items to reach the $200 threshold if you're close. Adding a lower-priced accessory like a scrunchie ($15-20) or headband ($25-30) may cost less than paying for shipping separately.
