TLDR; Not interested in you getting good rebates but getting there highest share of provision and data on you since bought by PayPal.

Used to be good and helpful, now it is a data collector for PayPal. In recent months no code worked or it did replace better or equal codes with Ref-Codes from Honey where they make more money themself. Also blocks codes from competitors when theyself have none, screwing the customer in the process.
