When any of you don't have enough to do, try to buy Enoz moth cake refills from somebody other than Amazon.
There was an article in Business Week a while back about Amazon. One of the story points was that Amazon was buying the dominant on-line nappy seller. Buying that competitor, they eliminated it as a market irritant and gained for themselves – Amazon – immense pricing power.
It appears they have also achieved that dominance in moth cakes.
There is one Japanese on-line grocery I can find that sells the cakes at half of Amazon's price.
But they require more information and commitment than I am interested in rendering.
Other than that, all roads lead to Amazon.
And once there the price is twice.
