I couldn't help feeling sad that a 10yo tree would end up like that just due to lack of care in a hardware store. At least in that chain's other local store, the bonsai is in the open under shade cloth. In this store it's all undercover with enough light but no sun or natural rain.
Anyway, I was back at the store and once again I was drawn to this tree - perhaps it was the despair and drama of the bare branches in pic 1. I spoke to the manager and he agreed to sell it to me for $20 which I thought wasn't money wasted because of the rock and the quite large pot (even if it is blue

It wasn't the only one in that condition - there was also a similarly-priced Trident equally dead with training wire very deeply embedded in its trunk & branches. It also had a nice rock and attractive pot so I took that for $20 too.
Both trees are still the pots and being tended daily. I know a miracle ain't going to occur in Spring but you never know ....
