We in Australia have Altronics and Jaycar that are nation wide.
Altronics have 6 stores nationally, and a network of Re-Sellers across the country, these re-sellers add their bit to the cost and don't have all stock, but can be very convenient in an emergency.
Jaycar have a similar arrangement, but they call their Re-Sellers Authorised Stockists.
Both appear to be doing well, both working in collaboration with local magazines, Silicon Chip and DIYODE.
Both have on-line shops.
One of the original electronics stores was Dick Smith, started 1968 mail order, grew nationally selling hobbyist and DIY components and kits. Evolved to computer and mobile phone as well.
Dick Smith the owner sold the company in 1982, buy 2008 they had dropped the DIY and components.
Basically they ended up in a market where they and just about every outlet in the shopping centre, strip mall or online was selling what they sold.
Stores were closed in 2016.
Dick Smith online is now owned by Kogan.
Many is the time you would say you were going to "Tricky Dicky's"
