Yup, it's true.
I randomly scanned in Blue Senturian at TRU yesterday morning and got the sale price. 24.99 is a fair price for that figure. It should not have been a Deluxe release. It's essentially the same scale and accessories as Magna Defender, and that was also 24.99.
It seems mainline stores are trying to clear out all their Power Rangers merch. Power Rangers will no longer have a shelf presence at stores soon, it's over.
If you still want the Ninja figures, Playtime Toys locations have them on sale for 19.99 each;
They'll have Wave 2 soon as well. These are all overstock from TRU.
