Fantastic, just what I've wanted. The Bundle deals are beyond useless and I was just looking for a way to block them. Actually getting a listing for the item individually is even better! I will say that the author should have an image showing how it works, as I assumed it was broken at first.
It adds a new link below the item that says "Just this one". Since AliExpress have stopped showing what is/isn't a bundle deal, you have to keep an eye out for that text to know that you're about to be hi jacked to the bundle page.
