As far as I am aware, Kodak were using Tetenal right up until the bankruptcy. That means that Kodak will have had to arrange a new supply chain, and this takes time. It's also likely that there were residual stocks of Tetenal-manufactured chemicals in the warehouses of retailers and that it's taken some time for the stock levels to vanish. If Kodak has found new chemical suppliers it could still take some time before the supply chain is re-established and as reliable as it once was.
As for Color Plus pricings, in the UK it can be had for £3 for a 36 exposure cassette from some online retailers. My local camera shop has it at £5 and says that they're not actually making much money from it....but they sell hundreds of rolls, not tens of thousands. It is likely they get less advantageous deals from suppliers than the big online retailers. They don't stock much Gold 200 as their price is £7.99, again they assure me they're not making much profit on it. In general, Gold 200 is much more expensive here than in the USA...possibly because availability of Color Plus affects sales of Gold.
