One of the key complaints about the earlier Disney DVDs was the $7 pricetag for the equivalent of a rental. At the time the rationale given was the convenience of not having to return the discs to a store. Unfortunately for Flexplay that amounted to a solution without a problem as Netflix, and later Blockbuster, had already found a way to eliminate due dates without charging $7 for each rental. It also became something of a public relations nightmare as the public became concerned about EZ-D DVDs piling up in landfills.
Flexplay has reportedly lowered prices in order to compete with both traditional and newer online DVD rental operations. They've also put some thought into the question of recycling. Retailers will double as collection points for the discs, and you can already request a pre-paid return mailer from the Flexplay website.
Of course the question remains, what need do disposable DVDs actually fill? If past performance is any indication the answer isn't promising for Flexplay.
