I've had all my purchases credited eventually with
Cashrewards in spite of many not being tracked automatically. I probably only get a 50% success rate on autotracking by cookie. To make
Cashrewards work for you unfortunately requires a lot of work on your part gathering evidence to submit for the eventual claim. For this reason I dont recommend it to anyone I know because I know they haven't got the time and incentive to be able to track things and follow them up for the time period required.
In my experience, you need to print every single piece of correspondence you get about each and everyone of your purchases to a contiguous PDF file. This means the e-mailed receipt from both the vendor+PayPal (if applicable), the order acknowledgement e-mail, the shipping advice e-mail, the payment received e-mail, the copy of the page of your credit card statement with all non-relevant entries redacted out and with the applicable exchange rate highlighted, the
Cashrewards acknowledgement of tracked purchase e-mail and any other relevant correspondence that happens during the lifecycle of the order between ordering and receipt of goods. On top of that, you need to mark-up the resulting document with the
Cashrewards cashback amount that was relevant when you ordered (1%, 2%, 3% etc.) because this changes frequently and you're not going to remember what it was 3 months down the track.
When you have this kind of a documented papertrail as evidence to submit for the missing purchase claim, the
Cashrewards people cave immediately and just credit you the rewards you're claiming without discussion or argument and they approve them immediately without the 2-3 month waiting time. It's a lot of work which is why I don't expect anyone else to do it and why I don't act as free advertising for
Cashrewards to my friends because I know they haven't go the time to chase it to this degree for 40c cashback, but it's what you need to do.
You need a rock solid reliable way of creating & editing the PDF document you'll need and the computer skills and wherewithall to file the evidence and ability/incentive to follow it up. If you can do it, then it works. If it sounds like too much trouble to be worth the effort, then yes,
Cashrewards is more like Norewards.
They promote it as easy and automatic, but it's definitely not. You do need to put in a LOT of time and effort for the very minimal returns.
