Time Your Purchases Around the Summer Sale

Built With Science runs its biggest promotion of the year during their Summer Sale in late June/early July. SimplyCodes historical data shows discounts reaching up to 30% off select products during this annual event, significantly higher than their typical promotional offers.

The Summer Sale typically lasts 7-10 days and includes both fitness programs and supplements. Our analysis of previous years' sales indicates that the best discounts appear during the first 48 hours of the promotion, with popular items selling out quickly.

Set calendar reminders for late June to check the Built With Science website daily. For maximum savings, combine the Summer Sale discounts with newsletter subscriber benefits for potentially stackable savings opportunities.

Verify Student Status for Significant Discounts

Built With Science offers a 25% student discount sitewide for verified students. SimplyCodes verification confirms this is one of the most generous student discounts in the fitness industry, applying to both digital programs and physical products.

Student verification is processed through a third-party service that requires an .edu email address or student ID. According to our assessment of the official store policy, verification typically takes less than 10 minutes to complete.

To claim the student discount, click the "Student Discount" link in the website footer and complete the verification process before adding items to your cart. The SimplyCodes community verified that this discount cannot be combined with other promotional offers, so compare available discounts before choosing this option.

Consider Competitor Codes for Additional Savings

Built With Science accepts some competitor discount codes at checkout. SimplyCodes data reveals over 1,200 competitor codes that shoppers have successfully used, providing an alternative savings method when Built With Science isn't running their own promotions.

The most commonly accepted competitor codes come from other fitness program providers and supplement companies. Our analysis shows these codes typically offer 10-15% discounts, though acceptance rates vary throughout the year.

Before completing your purchase, try entering competitor codes at checkout to see if they're accepted. The SimplyCodes browser extension automatically tests verified competitor codes to find working options without manual trial and error.

Use Sezzle for Interest-Free Payment Plans

Built With Science partners with Sezzle to offer interest-free payment plans on all purchases. According to our deep shopping research, this financing option allows customers to split payments into four equal installments over six weeks with no additional fees or interest.

Sezzle is particularly valuable for Built With Science's premium fitness programs, which can cost $97-$197. The SimplyCodes community reports that using Sezzle doesn't affect the final price but makes larger purchases more manageable for budget-conscious shoppers.

To use Sezzle, select it as your payment method during checkout and complete the quick approval process. Our assessment confirms that Sezzle can be combined with other discount strategies like newsletter coupons or seasonal sales for maximum savings.

Check for Autoship Discounts on Supplements
