Good to know

The things that don’t change for the sale.

Same lots, same reports

Sale orders ship from the same tested inventory. Every lot’s third-party certificate of analysis stays published on the Lab Tests page.

Stacking rules

HALLOWEEN20 can’t be combined with any other promo code or rewards coupon. On 10+ vials the automatic volume discount still applies, but the total discount on any Halloween order stops at 25%.

Halloween night cutoff

Orders placed before 11:59 PM Central on Oct 31 get the code. Weekend orders are processed on the next business day.

Questions

Halloween sale FAQ

Where do I enter the code?

On the cart page or the checkout page there is a coupon field. Type HALLOWEEN20 and apply it; the discount appears as a line item in the order summary before payment.

Is there a minimum order?

No. The code works on a single vial or a full bundle.

Does it work on products that are already on sale?

Yes. The 20% comes off the current shop price of each item.

Can I use it with the 10+ vial discount or a rewards coupon?

The 10+ vial discount still applies, but the total discount on a Halloween order is capped at 25% of merchandise, so 10 or more vials gets 25% off in total. HALLOWEEN20 can’t be combined with rewards coupons or other promo codes; your rewards stay in your account for a later order.

Can I apply it to an order I already placed?

No. Codes can’t be applied retroactively to orders placed before the sale or without the code.

When does it end?

11:59 PM Central Time on Saturday, October 31, 2026. The code will not work after that.
