Amazon might not be the only problem here. Best Buy, Walmart and even Indigo were all able to survive in the wake of Amazon so why not Pier 1? The problem might just be inertia to change on their part and embrace the online world of this century than anything else. An example of such inertia is ignoring the impact AI will have on organizations this decade (you can read my series on this here) and can easily be likened to moving against a moving train - only bad things can happen.
