medjooldates.com or nuts.com
medjooldates.com has a pretty good variety of organics. I ordered organic halawi dates 11 pounds for $40 and $12 shipping from cali to new jersey. The dates are amazing. Taste very fresh and they are really sweet and chewy. Only bad thing is the shipping took about a week for me but it was totally worth the wait.
nuts.com has organic medjool and pitted dates. They also have other varieties but only in non-organic. Pricing is good if you want just medjools ($90 for 15 pounds) and shipping for me was around $12. They are based in New Jersey so I get my dates next day every time.
http://shieldsdategarden.com/c-17-promotions.aspx where i always get my dates now. cheapest ones i've found and good quality. just got some khadrawis and they were a bit more dry than usual though but still good. i had some barhi and honeys from there in january/february and they were more soft. i would call them and ask them which ones are the most moist right now if that is something that matters to you.
