Lowes has it in their system as I bought some there [off the shelf] a
couple years ago.

Ask at the contractor desk. Try a real lumberyard or Ace/True
Value hardware.

[Though I have to say I think I paid $50 for the roll I got and 250sq
feet seems likely. If those guys don't kill you with shipping,
their price isn't bad]

Don't forget the tape.
