I can't bring myself to justify buying a cheaper deadener under the assumption you can just double it where needed. If it takes two layers of $1/foot² material to equal the deadening of a single layer of $2/foot² material, you're still spending $2/foot².
EDIT: The Lowes stuff mentioned above is peel & seal. "Peel & seal" is just a name we give stuff like that.
