You have to order $75 to get the free shipping, right?
As least as far as hops go, that is not a huge benefit in my eyes. It is pretty much the same price to ship 1 lb of hops vs 4 lbs (around $12). There are definitely times that I want to order some hops but I would rather just get 1 or 2 lbs...but dividing the shipping cost over 4 lbs always feels like a better deal. If I could get free shipping on a small order, I might be tempted to grab something unusual.
I usually time my YVH orders around a good First Friday sale. The last two years I have placed larger orders during their Black Friday sales (then I spend the next year trying to make a dent in my hop freezer supply!).
Looking at their grain selection, I notice they don't have a ton of variety. The biggest bags are 10 lbs, right? The price on 10 lb bags is lower than my local shop (say $15 there vs $20 at the shop) and maybe a little cheaper than places like More Beer, but not a price savings vs purchasing a full sack at a local shop.
