Border's demise, at least in Australia, was investing too much in the CD business. That lead them to renting much bigger space that they needed and increasing cost. When the CD years faded, they felt it hard on the balance sheet.
The CDs and DVDs were also horribly expensive compared to local competition, even if you used coupons. I honestly don't know why they thought they were in that business.
Our Borders had a tolerable collection of CS texts, diminishing in quality over the past couple of years. When they stopped getting new SF in on release days, I stopped buying books there.
