Presale: 20% off for the 2023 testing season!

We need your help: spring is a busy time at the Water Rangers warehouse, and we need to order supplies to assemble all our kits NOW! By supporting our presale, you ensure that we can buy enough supplies for all groups who need equipment in the spring. Plus, we hope you’ll agree, it’s never too early to start planning for the next testing season!

From now until December 31, 2022, you can use the coupon code PRESALE2023 to get 20% off your entire order and have it delivered by the end of March. Here’s how it works:

  • At checkout, use the coupon code PRESALE2023 to get 20% off eligible items.
  • PRESALE2023 gives you 20% off all regular-priced items in our store. That means restocking packs, testkits, notepads, t-shirts, and so many more!
  • This coupon cannot be combined with other coupons or promotions (like bulk discounts, sale items, other coupons you may have or co-branded kits that support our partners).
  • If items in your cart are eligible for a bulk discount (5-10%), this coupon will override the bulk discount promotion and give you 20% off those items.
  • This coupon is valid until December 31, 2022 at 11:59 PM ET.
  • All orders placed using this coupon will be delivered by March 31, 2023 – just in time for the launch of our official testing season!
  • Your entire order will be delivered in one package by March 31, 2022. So if some items in your order are not eligible for the discount, they will still be shipped at the same time as the other items.
  • If you want some items in your order to be shipped right away, you should place a separate order for those items.
  • If you have any questions, you can always contact us.
