Hi Jenny,
Thanks for taking the time to share this - I really appreciate you raising it.
The ad you’re referring to was originally part of our Black Friday campaign. You can usually tell from the ad name itself, which includes “Black Friday.” Unfortunately, old ads and pages can continue to appear online long after a promotion has ended, as content is cached and shared across different platforms.
That said, the ad itself referred to up to 40% off across the website, not necessarily 40% off every single product. We still have products discounted by 40% or more, so the message of the ad is still accurate at a site-wide level – just not always on every item at the same time.
The price shown on our website is always our live, current offer, and we don’t change it after checkout or hide fees. We also work very hard to keep our pricing the most competitive on the market for this type of product – our Sonic Pro is the best-selling ultrasonic + UV-C cleaner in the world, and we constantly benchmark against competitors to make sure our pricing stays fair.
When you contacted us, our team tried to help by offering additional discounts where possible, even though the original Black Friday promotion had already ended. I’m sorry that this still felt disappointing, as that was never our intention.
We always want customers to feel treated fairly, and your feedback genuinely helps us improve how we handle old ads and promotions online. Thanks again for flagging it, and I hope we get the chance to serve you in the future.
Thanks
