miminHi mimin,
We have always had a very restrictive business relationship with Aurifil where they set guidelines of what we could sell. We are not allowed to sell 50WT collections anymore so that is why we don't have drops up for it. I will say that even if we could, we would not be able to offer a better price on it then what you can find on Craftsy. They really do have the best pricing on Aurifil thread.
