Is it ok to store nuts like this - using a vacuum sealer device to avoid the need to refrigerate?

I think so that you can store nuts just like this and if you vacuum them than the shelf life may increase, i have not vacuumed them but its been long time that they are fine. The only thing is that you buy them from a good store or outlet, well i bought it online in bulk for my party from a href="http://www.nutsinbulk.com" rel="nofollow"http://www.nutsinbulk.com/a
