APR’s 4th of July Sale is live through Sunday at midnight EST.

That means the clock is already running on your chance to save up to 50% off.

Here’s the full tier breakdown:

Spend $300 → Save 30%
A strong tier if you’re placing a focused order or restocking a few key compounds.

Spend $400 → Save 40%
The middle tier for a larger research supply order.

Spend $500 → Save 50%
The highest savings tier — built for anyone looking to stock up before the sale ends.

This is the kind of sale where order size matters.

Adding one more product to your cart could move you into the next savings tier.

So before you check out, it’s worth reviewing your order and seeing which tier you’re closest to.
