What it is

A low-overhead version of a smart shop: an online store or marketplace listings for accessories and smart devices, plus a stall at weekend markets or fairs.

Your first three steps

  1. Pick a narrow niche, such as smart home starter kits or phone accessories, and research competitor prices
  2. Set up a simple online shop or marketplace account and order a small test batch from a UK supplier
  3. Enquire about pitches at local markets and car boot sales, then try a few weekends to see what sells
Who pays

Online shoppers looking for accessories and gadgets, and market visitors who want to buy and ask questions in person.
