I have been using Capital Kush since I first ordered with them. Unlike other companies on this app they actually give you the strain you order and are great with the no delivery fee. Also, I am glad they don't take 2 hours! like others to deliver...very prompt with regards to delivery.
My experience has been great with FlyDC. Unlike others they actually give me what is on the site and not say it is White Runtz and give me some random ass strain that doesn't match. I would give their authenticity an A+.
