Why should I use Repayclub for Rainbow Labs voucher codes?

Because every Rainbow Labs coupon, discount code and deal on this page is captured and verified by a real person, not copied in by a bot. The card already tells you what the code does and doesn't do – minimum spend, exclusions, first order only, expiry – we read the small print, note the bits that matter, and try the code on Rainbow Labs's own checkout before it goes live.

We keep looking after that, too. The date listed as "Updated" at the top of this page is when the Rainbow Labs list was last checked. Codes that no longer work are removed from the list on the same day. If it sounds too good to be true, it doesn't make the list. Cash back is the same – if Rainbow Labs pays cash back, the rate you see here is the rate you get, paid in real money, not points or vouchers, and you can use a Rainbow Labs voucher code and still get it on the same order.

One other thing – we only link to the official site of Rainbow Labs, rainbowlabs.co.uk. No fake stores, no "download this to get your code", no pop-ups. Choose a code, grab it, shop. That's the whole point.
