Best Buy isn't perfect, but in general they're much lighter on the 'advice' they try to give you. Their commission is in selling useless warranties, if a clerk does a good job I'll buy one as a tip.
There's no commission at Best Buy. IIRC, Circuit City was the last major US-based electronics retailer to end commission-based sales, and that happened in... 2004, maybe? Something like that.
Employees are judged on warranty sales, and when I worked at Circuit City back in the days when they, uh, existed, we were also judged based on profitability of sales.
