Many people find it easiest selling products rather than services. There really isn't a big problem with this if it is your preference, but it can reduce your margins. Our fruit was free while it lasted, but when it was gone, we no longer had a product. If you sell products, make sure you have continuous supply.
Examples of products that you can sell are:
Something you already make if you have a creative hobby
I’ve seen more than one Facebook page selling knitted clothes and other cute kids bits and pieces that people just rave about and often the outlay to set up this kind of operation is minimal.
Stuff you have at home and don’t use anymore
Some people are really great at this and even take it to the next level by buying stuff at lawn sales and second hand stores and then listing it on eBay. If you have a shopping bug yourself, this could be a good way to scratch the itch and make money at the same time.
