Before You Buy at JS Dental Lab
What shoppers ask most about JS Dental Lab.
›Can I combine multiple promo codes on a single order?
No, stacking multiple promo codes on a single order is not permitted at JS Dental Lab. You can only apply one promotional discount code per checkout, though eligible codes may still be used alongside ongoing site-wide automatic promotions.
›Are there any product lines excluded from discount codes?
Promo codes apply broadly across standard night guards and retainers, but clearance items and select limited introductory kits are excluded. Check code terms at checkout for specific product eligibility restrictions.
›Why was my promo code rejected at checkout?
Promo codes may be refused if they have expired, require a minimum purchase threshold that hasn't been met, or have already been used on a previous transaction. Ensure your cart meets all promotional criteria before submitting payment.
›Does the free shipping threshold cover the impression kit and final guard?
Yes, free shipping applies to orders over $100 and covers both the initial at-home impression kit delivery and the prepaid return transit of your molds back to the Hayward laboratory.
