Hello! Unfortunately the web app is no longer active, as pesky Ronald seemed to have got wind of the automatic survey filling magic and didn't like it. Maintaining the app and keeping the app working turned into cat-and-mouse and I didn't have the time!
If you're interested in how it worked, the code is on my Github!
Here in the UK, we get a voucher for a cheap Big Mac & Fries by filling out a survey starting with a code on a receipt from a previous meal. This Python web app uses the code from your receipt to automatically generate that precious voucher without doing the survey!
I'm practicing my dev skills! I'm using Python with Selenium running in a Docker container, and Flask to handle the frontend. Cheers Ronald!
