What is cheaper to use on a one time basis?

Question

What is cheaper to use on a one time basis? A sandwich bag (generic brand) or a piece of plastic wrap (about a 9" - 12" length - generic brand as well)?

Answer 1

Plastic wrap

Answer 2

The plastic wrap ... asuming it doesn't fold over and get stuck to itself, so that you end up having to cut off another piece.  But, for freshness, the ziplock baggie is best....

Answer 3

Plastic wrap is designed for one-time use.

Baggies cost more, but can be re-used.
