Clearance sale on packaged food

[aces]

CampingSurvival.com is running a clearance sale on some survival and food storage products today.  Not sure how long this sale will last.  The discount is an average of 10% off their usual prices and includes food from Mountain House, Yoders, Augason Farms (instant milk and dried fruit items), Future Essentials,  Keystone canned meat, Bega canned cheese, Datrex and Mainstay food bars, and Star MRE products.

If you hit "Details" in the product listing, it will often give you the date packed and the expiration date.
A few that I looked at were Dec. 2019 (so 18 months left.) 

Shipping is not free with minimum purchase with this vendor.  Their policy online says if you don't like the shipping quote, you can call them to see if they have any alternatives to cut that cost down. 

Interestingly, they are out of stock on several water treatment products.
