Puzzle glue

Hi! I’m new here but not new to puzzles. I collect glued together completed puzzles (often missing pieces for character). I have been doing this for years and have made quite a collection without spending much on my puzzles, as I love to find them at goodwill. I do however, spend so much buying puzzle glue one 8oz container at a time. Is there an alternative glue that can be? Hopefully one with bigger containers. I’ve searched online for puzzle glue in bulk and can’t find it. If there is a better page for this, please lead me
