Yes, you probably can. Many people want to support their community, but still want the convenience of shopping online. Not all small businesses have an online catalog, but some very small businesses are only online.
You can shop local on Etsy, too. From the home page, click on shop local and enter your location. In the browse section, you have to select a category before the shop location option appears. You can select location on search result pages too.
You may be surprised how many Etsy shops are owned by people in your area. Other online shopping platforms probably have a location option too, you just have to know to look for it.
Good luck shopping and Happy Holidays!
My shop is Debnests.
