During the first week of the price cuts, Tasos found that 10 percent of Trader Joe's regular customers who shopped at least twice a month defected to Whole Foods compared to the previous week.

Regular customers at TJ's who went to check out the new prices at WF right after the Amazon takeover are necessarily "defectors." Only time will tell on that score.

Amazon gained customers at the expense of its rivals

Aka, capitalism. The horror, the horror.

[a fool in paradise]

Trader Joe’s customers will continue to go obsessively to Trader Joe’s because only TJ has TJ’s merchandise. It’s company branded.
