The tool did function for a short while, during which it successfuly reclaimed a few hundred dollars in refunds. However, it broke when a courier site introduced reCAPTCHA at their login and Amazon made UI changes to their order page. I'm now at a crossroads, contemplating whether the upkeep required to ensure the app keeps working is worth my while, given how niche the potential market is. I am not sure if I can make realistically make money from this. Would love to hear insights or suggestions.
For reference, you can check it out at https://taxrefunder.io, although the core functionality is down at the moment.
