AmirDirect via Amazon offers Prime members its Amir 2-In-1 Clip-On Lens for $28.99 with free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, shipping costs $6.33.) That's tied with last week's mention and the lowest total price we could find by $4. It converts from a 0.6X wide angle lens to a 15X macro lens, and fits most cell phones.
