Much better than waiting for it to be delivered by Amazon, and hoping it hasn't melted on the way.
$25/kg is a fairly good price, especially with >85% (anything else is expensive sugar, high fructose corn syrup actually, with hydrogenated "vegetable", i.e. soybean, oil).
Are the >85% dark bars dutched?
I heard that 85% is the highest dark without dutching.
