Rainbow Labs Coupons FAQ
- How do I apply a promo code at checkout?
Simply add your items to the basket and proceed to checkout. On the payment page, you'll find a field labelled 'Promo Code', 'Voucher Code', or 'Discount Code'. Enter your code and click 'Apply'. The discount will be instantly deducted from your order total.
- Why is my voucher code not working?
Your code may be invalid if it has expired, doesn't meet the minimum spend requirement, or is for a specific product category. Please check the terms and conditions of the special offer. Ensure you've entered the code correctly, without any extra spaces.
- Can I use more than one discount code per order?
Unfortunately, no. Our system only allows one promo code or voucher to be applied per transaction. You cannot combine multiple discounts, but you can choose the one that offers you the best saving on your order.
- Do Rainbow Labs vouchers expire?
Yes, most vouchers and promotional codes have an expiry date. This will be clearly stated in the terms and conditions of the offer. We recommend using your discount as soon as possible to avoid missing out.
- Is there a way to get free delivery on my order?
Absolutely! We frequently run special offers for free UK delivery, typically when you spend over a certain amount. Check our current promotions page or look for a promo code specifically for free delivery before you complete your purchase.
- Where can I find the latest Rainbow Labs discount codes?
For the most current promo codes and special offers, sign up for our newsletter or follow us on social media. All active vouchers are also listed on our dedicated 'Special Offers' page on the website.
- Can I use a discount code on sale items?
This depends on the specific promotion. Some vouchers can be applied to already reduced sale items for extra savings, while others cannot. Please check the individual terms and conditions of the promo code for clarification.
- What is the difference between a promo code and a gift voucher?
A promo code is typically for a percentage or fixed-amount discount or free delivery and has specific terms. A gift voucher is a pre-paid credit you purchase for someone to redeem against the cost of their order, acting like digital cash.
