I can buy a pound online, pay shipping, and it's still half of what LHBS charges for a pound, let alone 16 individual 1oz packs. I double vacuum seal and freeze, and they would probably keep a lot longer than it takes me to use them up. Remember, the hop growers and brokers keep them for years. There was a discussion here recently that noted that HSI is based on room temperature storage, and that degradation decreases so much with temperature, that at home freezer temps (0°F) it is negligible, not even worth calculating.
I'm not worried about freight. I want trying to get anything special. Just the basics. Cascade, citra etc. Lukily we have Amazon prime haha.
I've found hops can be pretty pricy on Amazon, which can more than cancel out the free shipping. Try Yakima Valley Hops, Hops Direct, Hop Heaven (on eBay) or do some more searching. These dealers charge so little per pound, you'll pay shipping and still beat Amazon Prime. That's how I pay so much less than LHBS.
