Correct me if I am wrong but I think loophole and bargains are different;
Bargain:(Proposed by official means)
a thing bought or offered for sale much more cheaply than is usual or expected.
"the table was a real bargain"
Loophole:(A unsolicited "sale")
a small mistake in an agreement or law that gives someone the chance to avoid having to do something:
tax loopholes
The company employed lawyers to find loopholes in environmental protection laws.
Please forgive me if I have done anything wrong by reposting/paraphrasing this is my first post…
