When I wrote HTW to ask for replacement of outdated Lamotte ColorQ Pro 7 reagents (some would expire in as little as 4 months), they responded:
"Unfortunately, due to stocking and as advised in our policy, we do only guarantee our reagents for up to 3 months". Even more unfortunate: HTW does NOT post this rumored "policy" anywhere on their site (as of this writing Oct '16). HTW acts as if this is beyond their control (see HTW response below), so I guess we can all be thankful that HTW does not sell milk:
"Regardless of the normal shelf life. We have considered removing them from our site, but found customer still have a high demand for these. As long as you do understand, we only guarantee them to have no less than a 90 day life, then we will continue to stock them."
I would understand if HTW would put this "policy" on their site adjacent to the "Purchase Now" button.
