I recently worked at The Source. The Source has nothing to do with Radio Shack at all. They are owned by Bell (BCE) and is pretty much a Bell store with a bunch of other crap. Pretty much all the emphasis is put on selling home and cellular services. If you are into that type of sales atmosphere (I wasnt), you can make ALOT of money at it. There are commissions for selling home and cellular services, some items have 'spiffs' which can be money or points towards prizes, and then commissions based on general sales totals. I have made $100 off of single cellular sales combining high commissions, spiffs for added 'ACP' warranties and for selling particular phones (say $25 for the activation, $25 from the warranty, and $50 for a featured phone).
They are good to their staff, there are incentives, medical and investment benefits, paid holidays, and opportunity for advancement.
The other electronics is just to get you in the door to have conversations about the services. They have several store brands, Nexxtech, narlyfish, Fluid, and Headrush. Some of it is good, some is crap. I have seen $10 Headrush earbuds made by Bose, Fluid TVs made by Toshiba, and many other examples. I have also seen the generic 'made in china' crap.
Their business model is working quite well, they are one of the fastest growing companies in Canada, sitting at around 720 locations, adding about 20 new locations a year. Radioshack should be heading the same way The Source did. Almost no one builds things or repairs them anymore, you just toss it out and buy another or replace and entire plug and play components.
Last year we had 3x the amount of electronic components, 2/3 of which got sent back to the warehouse. No one buys it, and it is just taking up shelf space. Only a few times a week will someone come in and buy a $2-3 part... not worth to keep around.
