I believe the answer is:

haggler

I'm a little stuck... Click here to teach me more about this clue!

But I can't explain it at all! Could you help me understand?

(Other definitions for haggler that I've seen before include "One bargains on price" , "One seeking bargain" , "One arguing over price" , "One trying to get price reduced" , "Dealer" .)

I've seen this clue in The Times.
