Push back more strongly. My partner at the time had been working at a Toys'R'Us store for many years. She said right up to the last day store traffic was as strong as ever - think last minute shopping for your kid's friend's birthday party, buying toys for your own kid's birthday etc. They had significant traffic and sales throughout the year, not just holiday season. Buying a bicycle for our kid? You're going to want to do that in person. You're a mediocre parent that wants to placate your "annoying" kid? take them to Toys'R'Us and let them shop for something. People really underestimate how well TRU was thriving as a brick-and-mortar store.
Also, contrary to what the article says about not figuring out online shopping and logistics, she said associates spent a majority of their time pulling online orders for same-day in-store pickup, and that business was steadily increasing.
Too much debt killed Toys'R'Us, not Amazon. I don't know if it was all acquisition debt, or if they loaded up afterwords to strip-mine value but either way it was the debt period.
