Can I ask why you're buying flax seed? It's not really as healthy as everybody likes to make you think. Flax seed contains omega-3s, but not ones that are very bioavailable to humans. ALA (alpha linolenic acid) is an omega-3 unsaturated fatty acid that is frequently found in plant material. The problem with ALA is that humans do not have the proper enzymes to convert these to functional omega-3s, such as EPA and DHA. Sure, flax seeds are good for the fiber, but there are much cheaper fiber sources out there. I'd personally say spend the extra money on honing your diet in... or just save your money.
