Current Sale

The sale set rotates on a schedule rather than running continuously, and only in-stock material is ever included. Each tile shows the original price beside the sale price, so the discount is checkable rather than asserted against a figure nobody paid.

A discounted vial is the same material as the full-price one: same release specification, same batch documentation, same certificate where one is published. Nothing is discounted because it is close to expiry.

Volume tiers apply per line rather than across the basket, and they compound on a sale price: the quantity break comes off the discounted figure, not the original. The one thing that does not combine is the companion-compound add-on offer, which is not applied to a vial that is already marked down. If nothing is on sale today, the full research catalogue lists every compound with its current price, and published certificates are available whether or not a vial is discounted.
