BAL inventory & manipulation ?

.

I got my latest 2 pallets of step 3 is manufactured in Dec, 2016. In my memory, their inventory was peaked in Mar/Apr, 2017, that means they still manufactured in first qtr in 2017. Some posters said they found 2017 August version in Coles etc.

I think there should be enough stock available as I guess they have 2 or 3 month inventory available, but it seems supply is very tight right now. So I wonder if someone or company is manipulating the market.

If sale volume is really big, I will change my sentiment to buy.
