Rules:

1. Be civil


Attack the argument, not the person. No racism/sexism/bigotry. Good faith argumentation only. This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban. Do not respond to rule-breaking content; report it and move on.


2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.


Obvious biased sources will be removed at the mods’ discretion. Supporting links can be added in comments or posted separately but not to the post body. Sources may be checked for reliability using Wikipedia, MBFC, AdFontes, GroundNews, etc.


3. No bots, spam or self-promotion.


Only approved bots, which follow the guidelines for bots set by the instance, are allowed.


4. Post titles should be the same as the article used as source. Clickbait titles may be removed.


Posts which titles don’t match the source may be removed. If the site changed their headline, we may ask you to update the post title. Clickbait titles use hyperbolic language and do not accurately describe the article content. When necessary, post titles may be edited, clearly marked with [brackets], but may never be used to editorialize or comment on the content.


5. Only recent news is allowed.


Posts must be news from the most recent 30 days.

No opinion pieces, Listicles, editorials, videos, blogs, press releases, or celebrity gossip will be allowed. All posts will be judged on a case-by-case basis. Mods may use discretion to pre-approve videos or press releases from highly credible sources that provide unique, newsworthy content not available or possible in another format.


7. No duplicate posts.


If an article has already been posted, it will be removed. Different articles reporting on the same subject are permitted. If the post that matches your post is very old, we refer you to rule 5.


8. Misinformation is prohibited.


Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.


9. No link shorteners or news aggregators.


All posts must link to original article sources. You may include archival links in the post description. News aggregators such as Yahoo, Google, Hacker News, etc. should be avoided in favor of the original source link. Newswire services such as AP, Reuters, or AFP, are frequently republished and may be shared from other credible sources.

Key Points

Walmart is rolling out digital shelf labels and expects the technology to be in all U.S. stores by year’s end. Kroger also has begun experimenting with the technology.

The nation’s largest retailer says the digital price tags help associates do their jobs better and stresses that prices on items will be exactly the same for every consumer in every store.

Some legislators are wary of the technology’s potential to be used in dynamic pricing models that disadvantage consumers, with Sens. Jeff Merkley (D-Ore.) and Ben Ray Luján (D-N.M.) introducing a bill to ban it.

There is legal obligation to honor the shelf tag if it says a product should be lower than what it rang up for. Otherwise it's essentially a bait and switch, and can usually get a store in trouble if a customer complains to the right people.

At the federal level (in the USA at least), there isn't. Some states might, no law covering the entire nation.

Otherwise it’s essentially a bait and switch, and can usually get a store in trouble if a customer complains to the right people.

The legal barrier for "bait and switch" is higher than that. Bait and switch is if the price is intentionally lowered and advertised, then raised or not offered when the customer tries to buy. If a customer took one of these "expired shelf tag" situations to court, the retailer could easily point to their sale promo from the week before showing the price was valid at that time, but that the old shelf tag hadn't been properly taken down. The retailer would win, but the retailer knows this too and the cost of legal representation, bad press, and losing a customer usually isn't worth winning the legal argument, so they usually just honor the mistakenly lower price and move on.
