I'll give you a reason not to get Honey.  The Honey, well not exactly popups but images that show up in the pages of shopping sites can cover info I am trying to see/read.  In particular, it loves to cover up the check out price with an offer to try codes. That's super annoying if I want to look at the cost in my cart, but I am not ready to check out. I've found that really annoying the last week or so.  But it does save you money so I will probably leave it enabled for now.
