Y'know, one thing I would pay a premium for is overnight shipping via UPS or FedEx, especially for micro or instant. I know I need to plan a little better, but sometimes you just run out, and being able to get a batch the next day, I'd pay for that. USPS sucks for express shipping. (Not disregarding that KWK is available on Amazon Prime, but there's no micro available w/next day shipping).
A bit off topic, but my 2 cents. Sorry for the noise. ;-P
