MKM told me before I paid rather than substituting. A thread about that

One line in my MKM order was out of stock and I was told before I paid, rather than being sent something adjacent and finding out on the doorstep.

I want to make a small argument for why that single decision matters more than it looks. A silent substitution destroys the only check you have: the lot on the vial against the lot on the paper stops meaning anything if the contents are not what you ordered in the first place.

Five orders since. Storage conditions volunteered without my asking, both times I noticed.
