We all wear clothes (at least some of the time). Which, of course, makes the business idea of cleaning soiled laundry an obvious hit. In fact, the self-service laundromat industry in the US is worth more than $3 billion, with many related businesses such as a mobile app laundry service, a real rolling mobile laundry service, and home laundry pickup & delivery services springing up each year. Here’s one way you can cash in on the trend as a side business idea.
My 10-year-old son brought home a book from our park’s free library box. It was a biology textbook – teachers edition. He said it looked interesting and hey, it was free (having no idea you could sell it). I scanned it in my Amazon seller app and realized it was worth around $150. He was so excited. We listed it for sale for $130 and it sold! Going to tell him, he just made $130!
