Today only, Tanga offers the Telescopic 8x Lens & Tripod Kit for iPhone 3 & 4, model no. 72-14512, for $16.99. With $4.99 for shipping, that's the lowest total price we could find by $4, although we saw it for a buck less last week (since expired). This item adds extended range and functionality to your iPhone's camera. It features an 8x optical lens, mini tripod, protective case, and more.
