Well, took a chance and decided to place a small order with SoS, got some really obscure beans to play with. In any case, ordered after their business hours (probably?) on Monday, 12:36 PM my time, 6:36 PM London time, but have received nothing but an email confirmation that the order was placed almost immediately. No other communication thus far, so a whole business day with nothing. I must say that has not happened with Herbies, my usual ordering site. It has happened with Attitude, but only during big promos. We'll see how many days they take to actually ship out my package.
The good thing is that I don't have a need for beans right away so I can wait. Just comparing SoS' service thus far against what I have experienced with 3 other banks/sellers. As far as speed of fulfilling order, its Herbies> Alibongo > Attitude > SoS.
