Return Air Plenum

Horizontally operated furnaces and air handlers should have a return air plenum that looks like this
because it is aerodynamically correct and easy to seal
.... but...there is often not enough room in the attic to use it.
A simple, uninsulated RAP-18" like this sells for $50 but costs about $90 to ship FedEx.

This RAP, fed with multiple returns, allows for an efficient flow of air through out your house.
It costs about $230 fully taped and insulated and also costs about $150 to ship out via FedEx.

.... So ...?
How do I attach return air to my A/C?
