Plastic Window Film 3m

Cheap Double-Sided Tape for Insulating Windows with Plastic?
I want to add plastic sheeting to my windows in preparation for the winter months.
I noticed that those Window Film kits are rather expensive for the paltry contents inside. Buying the plastic film apart from one of the window winter kits is easy and cheap.
However, the double-sided mounting tape is ridiculously expensive, even if i buy it a la carte.
Is there a very cheap alternative to this mounting tape? For example, 20 feet of 3M double-sided mounting tape for $3 is a bit high. That will get me through maybe one window.

i use thin strips of card board and a small stapler,
