A Consumer Reports, Groundwork Collaborative and More Perfect Union investigation found that some grocery prices differed by as much as 23 percent per item from one Instacart customer to the next. In an inadvertently sent email, the company calls one pricing tactic “smart rounding.”
Well no shit. If a department store can change the prices of items at the click of a button, you have to expect them to do it to make more money.
There are currently now laws against this kind of abuse, to my knowledge. There was no need for them when you had to pay someone to manually change all price tags.
