I have done a fair amount of business with LLL and had them up on the same level as Josh's frogs for beginners in the hobby.
As Bill said the issue I have come across with Josh's frogs recently is they can not with any certainty tell you the lineage of the frogs you purchase from them. Mostly it is because they have multiple breeding pairs and don't keep the off spring separate (which I don't fault them on), but the more I learn about the hobby and the more I get involved in breeding the more I value having those questions answered.
Back on topic.
I have not contacted LLL. I had a couple other issues with them recently and this just pushed me over the edge. I am not sure what they could do now to salvage me as a returning customer. Which makes me sad.
This threads original intent was to bring the fact that LLL is buying and reselling frogs from USAFrogs to the attention of this community. It is up to each person to do with that information what they see to be the best choice for them.
