I've been buying Lamotte reagents for 4 years. Many times I have had to request a refund due to getting old or nearly out of date reagents. But NOT since I started buying from eseasongear. Everytime the reagent has plenty of time before expiration. The most difficult one to get fresh is this CH2. It only has a 6 month shelf life. When i got my last bottle of it from eseason it had a full 6 months to go! Hooray.
