Terrible purchase experience

Of the 10 bottles I bought, 9 will expire in 2 months after purchase. Shameful

I’m re-ordering soon..

Great product;been using it for years. Kudos and thanks to this site for keeping it available while every other site says it’s unavailable;don’t know why, don’t care. This is a great product that I depend on and need. It acts as nature’s anti inflammatory when taken on an empty stomach and a powerful digestive enzyme when taken with food. I plan on re-ordering in about a week or so.
