Amazon offers its Prime members the The iPad Commode Caddy for iPad + Roll Holder, model no. PAD-TSB for $34.99 with free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, it adds $13.09.) That's the lowest total price we could find by $11, although we saw it with pickup for $3 less in December. It can hold second- to fourth-generation iPads with its flexible 10" gooseneck. It also features a snappable paper roll tube.
