AB 20th anniversary sale storing LME

I ordered 5 kits from AB will be here tomarrow and they recomend using LME in a month or less, which is no problem, but I would like to get 5 more kits before the sale runs out Sunday. I will probably brew them right away because I'm trying to get about a ten keg reserve. If I did want to keep them for more than a month does anyone know how to preserve LME. I thought about freezing it or canning it in mason jars like honey or molasses. I don't figure on keeping them much more than a month, then it will be nice enough weather to AG.

I think you can freeze it. Heres a similar thread on freezing LME:

Edit: That thread, and I have seen it in other places, says that you can add vodka to the top of the LME to increase shelf life (eliminates mold and bacteria growth)

I found a good article on storing your brewables:

Liquid malt syrup that has been opened, or is sold in bulk plastic containers, has a much shorter shelf life. While buying malt syrup in this form is normally less expensive, it must be used in less than 3 months, or the syrup will degrade or even grow mold. If you have malt syrup in this form, the best way to store it is in the fridge. Pick the smallest possible container to eliminate airspace and avoid oxidation. While the extremely high sugar content inhibits yeast activity and molding, over a three- to four-month time period the syrup will lose its freshness.
