I have two codes for a free box of Factor meals, fwiw. No expiration date listed. New customers only. Shipping was $11 when I did it. Well worth imho, although I wouldn’t subscribe to this regularly–not particularly healthy due to sodium and fat levels.
Factor75.com/free-box is the place to use the code.
PM me if you would like one; I’ll (try to) delete this post when both are gone.
