Whistle $20 off email newsletter codes
Newsletter codes are one-time-use promotional codes provided by Whistle to individual customers. On Knoji, you can share your newsletter codes for any store and receive credits for gift cards in exchange. We make these codes available to other shoppers here.
How to use: To use any newsletter discount code, simply click or tap on one to copy it to your clipboard. You'll be taken to Whistle's website where you can finish your shopping. During checkout, enter your newsletter discount code into the "promo code" box. Your discount should be applied and your total purchase price reduced by $20 off.
If your code does not work, that's OK, just try another code. Single-use codes expire quickly so it may take a few tries before you find an unexpired code.
