Maybe 4-5 months ago? I was surprised as they were indeed very good daytime diapers and were priced about where they ought to had been. I can only surmise they must not have been selling well enough OR it was due to a supply chain issue. IF they were flying off of the shelves and making Northshore a good return on investment you can bet your bottom dollar they would still be available, one way or the other!
They did about 5 months ago. Northshore Adam said that there just wasn't enough customers buying them anymore, because they are seeing a lot of customers switching to Megamax. Thankfully, the plain white version will stick around for the foreseable future.
I'm afraid there will be nothing you can do about it in the US, but if there's someone reading this in Europe, http://france-abdl.fr still sells what they have of their last container shipment.
