$7 is extremely cheap. Find out what it entails. I clean my shoes to reduce my stress level. I get the goodfellas shoe shine box jokes all the time. Thing is I clean my shoes to the point they look immaculate. My philosophy is nobody will clean your shoes better than yourself because they are yours. I watched a ton of youtube videos to teach myself how. As well as what chemicals/brushes work and don’t work. Just don’t want you to pay $7 and get a piss poor job done.
You need to understand that you can list anything at whatever the F you feel like. it does not mean they are worth that much less anyone will pay it.
