Amazon has the PIG Form-A-Funnel Flexible Draining Tool – 6.5" x 14.5" on sale for $ 4.99 + $ 5.50 shipping (+ tax for some.) The majority of amazon reviews are positive. Lowest price in comparison I found was $ 15.08 from another amazon seller.
I bought a few as gifts and the shipping charge only increased a few cents to ship the additional units. Cheap novelty gift for a backyard mechanic.
