I've only ordered once from SoS, and received it with n/p in about 12 days. I have only some minor complaints about SoS: they don't tell you on the site who produces their freebies, though I've heard they will if you mail them. I received what turned out to be CropiCanna - a bunch of fruit named strains that you have no idea what genetics may be in it - I'll likely never use them.
I concede that Attitude is usually more expensive, but that's where I'll go for non-Sannies' beans. Several orders with never a problem, and their website is extremely user friendly. Their rotation of freebies has too many auto-fems for my liking, but normally they rotate reliable name brands. Use promo code 420 and get 10 % off, which covers shipping in the cool tin box.
