thomas and friends mini series

I popped into the Fremont, CA Target at 7pm and picked up 1 of each number from the open 2017/1 box. Almost got the entire series, but am missing 1:
upc# 887961447699

Before anyone gets excited and runs the to store after calling the store and verifying they have these in stock, heads-up; (unless this was discussed before, and I feel ashamed for not forgetting about it)
Fisher Price seems to use the same UPC for all waves, at least same one for 2016/3. The sales associate who pulled out this box for me said he had no other boxes and that he doesn't know when he will get more, and the ones in store turned out to be 2016/3.
Looks like there is no way to verify availability unless we actually go to each store and check.

Although I did get myself --umm for my son-- a Streamlined Thomas and Ashima T&P engines.

Does anyone know how many is there in the unopened display box?
