There's not many ways a Distributor can shine over other Distributors and those are surely, Service, speed, accuracy, aftersales Service and the freebies.
As Bonequicha rightly says,
They have no control over bean quality - other than not to distribute a Breeder's seeds due to poor quality. However, they also want to distribute as many lines as possible - so, perhaps they are not so choosey on who's beans they sell.
This is a "Buyer beware" situation. Especially with the number of new "Breeders" popping up from nowhere every day.
I've learnt my lessons, lost money and received crap - but not from Attitude or Original (another thread).
Sure, these big Cos can screw up an order and it is frustrating, but they will put it right - deal with the small unheard of ones at your peril.
