Buy one, get one free

Add any two eligible vials and the lower-priced one is free. Mix and match across 33 products — no code needed.

How it works

  1. Add eligible vialsLook for the “Buy One Get One” tag. Different products and sizes can be combined.
  2. Every second one is freeFor every two eligible units, one is free, starting with the lowest-priced. Four units get the two lowest-priced free.
  3. Applied automaticallyThe cart shows your saving and checkout applies it. No code to enter.

Applies to one-time purchases of eligible products. A discount code can be used with it: the code comes off the Buy One, Get One Free price, one code per order. Research stacks are already priced below Buy One, Get One, so they aren't counted again; supplies are excluded. Free shipping still applies over $150.
