The thing I always was frustrated with was we were threatened into selling warranties that would not cover anything other than factory defect. For each warranty we sold we got anywhere from $1-$4 on cameras, peripherals and $5-$10 on computer warranties.
We almost never had anything in stock. Probably 50% of the questions we got we sent to other nearby stores.
The other problem I had was the amount of time it took for people to be able to buy laptops. Somebody would pick out a laptop, then I would need to check the stock on the item, then go back up to the front of the store grab a UPC sheet for that laptop for the person to get checked out, and we could only ring the person out through the tech shop, so I would need to page a manager to unlock the register and check them out. Usually it takes at least 5 minutes for the manager to come over, then the manager would raz you for not selling warranties as we walked over to laptop lockup. We had to Find the matching UPC laptop, which generally we could not find because somebody took that one already (in which case we would have to return and re-ring the poor guy's laptop), but if we do find it, we fill out a checkout form. walk out and hand it to the guy. This process usually takes 30 minutes if the store is at all busy.
The other thing was the stores stocked so much shit in them. Paper.. landscaping software.. desk gadgets..lame PC mod stuff & lame cases... off brand overpriced external drives.. offbrand networking devices.. Video Games.. Books.. We spent more time moving old shit around than we actually spent on the sales floor. They should should have less selection.. more stock. They needed to go through with a fine tooth comb and fix that.
It was a great job in the summer because it was indoors, pretty easy, the hours were flexible, the people were okay, but I have seen a big decline in the last few years.
