I like doing business online because it allows me flexibility. Selling online is a good sideline. There is a huge market because everybody goes online nowadays. Also, I have control over my time. I am not pressed for deadlines and such. The only thing that's holding me back are the items I sell. When I had plenty of time -before my nieces moved in with us- I had time to make scrapbook pages or personalized wooded plaques to sell, but now, hardly. My friend, and co-teacher, Mike, mentioned about his brother's ebay store. His brother buys his wholesale products from wholesalers that are also found online. Amazing how flexible these wholesale suppliers are. Short of saying, you can sell almost anything you like and still get it with at wholesale price.
Methinks, given much attention, selling online can be a a very good sideline. Who knows, you might even give up your career and do this full time!
