I dont see it either. Search for Reader Rabbit on Amazon and you get 36 results. All of which are on sale. I wouldnt want to compete with 36 other near-identical products sharing the same brand, but costing $25 less.
I know what you're going to say; Excuses, excuses. And I agree there is no reason they shouldnt be trying to maximize every effort to sell product.
Perhaps, the cost/earnings isn't there. Perhaps its in the cards (it can be done within a day).
