Last Friday, my Nurse Friend recommended the Too Good to Go food app. So far, only the Cookstown Branch of Tim Horton's offers anything locally. Some other places are driveable, for me, but taking the bus to Belfast and back to collect grub would be counterproductive; wastes the money I planned to save.
At the moment, I have enough food. But the App is on standby. More local places might cop on to the app.
