If by “killed”, you mean I use Target, Home Depot, and Walmart pickup without issue.
The fact that two discounters are also riding the runaway bucket to the bottom says more about the threat that Amazon poses than their ability to beat Amazon long-term.
With things like ApplePay, you can get buy with two clicks, which is only slightly more annoying than amazon.
I do wish Amazon would adopt ApplePay, too.
