Sorry for the delays. We can't control it, but we still are responsible for your overall experience.
Generally we monitor this and send replacements if coffees get stuck. We will probably do this automatically soon. I understand this still isn't ideal.
We definitely are looking into allowing a FedEx option. We have a pretty complicated product, so it is nice to use a single shipper for now, though.
One thing that could help is picking coffee directly from a roaster that is close to you. If you tell me where you live, I can send you the best roasters for a consistent experience.
