I had the same thought/hope: that someone else will use this as an opportunity to step in and re-raise the bar, for trustworthiness and supply chain integrity. Competition is good.

In the meantime, I've recently been experimenting with buying from other vendors for things I normally buy though Amazon, and with which I'd had trouble: particular brands of clothing, computer parts, water filter cartridges.

I've also been trying brick&mortar, and anecdotal results so far are that it's so-so or bad for selection, good for assessing quality and expected item and condition, and good for lead time.

Separate from browsing store inventory in-person, in-store pickup of online orders is consistently poor-to-ridiculously-bad so far (5 out of 5 times). The anecdotally worst major retailer thus far is surprising.

(Incidentally, I also realized, given the distinctive look of the Walmart shipping box in the lobby of a condo building of about 100 people, that I'd never noticed any of my neighbors buying from Walmart before. I suppose there's some stigma and general objection to Walmart to overcome, though Amazon hasn't been doing so great on reputation either in the last couple years. My two Walmart orders thus far have been wholly positive experiences.)
