Amazon offers Prime members the KidsFunwares TriceraTaco Taco Holder in Green for $12.95 with free shipping. Excluding the below mention, that's the lowest price we could find by $5, although we saw it for $2 less in July. It holds two tacos and is dishwasher safe.

A close price: Groupon has it for $9.99 plus $3.99 for shipping.
