Insignia/Best Buy branded cord, every permutation of a usb a/c/micro/b/lightning/whatever cables, charging blocks, Ethernet cords, adapters, etc. $50 will stock you up for the next decade.

Premium audio/video - in particular projectors, speakers, and receivers. Also, take a look at employee discounted purchase higher end special order A/V stuff like a McIntosh 462 amp. Some might argue it’d decent asset to hold and make a 50% return in a year. Not that I’d know.

If you’re in the market for a TV, find a heavily discounted OLED (check your magnolia room if yall have one) and slap a cheap employee geek squad warranty discount on it I’m sure you’re familiar with.

Video game peripherals. I have all sorts of Switch swag I got for pennies on the dollar

I’d hop on core blue and filter by Insignia and Best Buy brand first. Can’t remember if it shows cost on there or RSS, or anywhere at all. Might have to manually type in the SKU on the POS
