I did a recent order that included 3 jugs of an item that was from a very small lot of a powder not normally listed.
Turns out, Jeff's supplier did him wrong and it was not a good batch.
I immediately contacted him.
He looked into it, apologized and offered to make it right.
I ended up working out a deal with him and now will have 24# of WC680. This goes with with a healthy stockpile (around 28#) of WC 844 part of which came with the original order.
Jeff did me right and I will not hesitate to do business with him again if the occasion comes up (I am more stocked up than ever before).
