They'll never go bankrupt because they have enough remnants of ignorant mall customers to buy overpriced cables and because they're the last major game left in technology retail besides big box stores.
Not sure if the employee discount is still the same (close to cost) but a friend of mine worked there around 20 years ago and I was shocked how cheap he could get cables.
When I worked there, margins on the cables were something like 85-95% so employee discounts were huge. On other items, TVs and such, the margins are much much lower so at most you got $25-50 off of the sale price.
