## Walmart's pricing promise
Walmart CEO John Furner claims they price products, not people, using AI tools like Sparky.

> We price the product, not the person
## Paper price tags
Old paper price tags showed fixed prices without customer data, making them simple and transparent.
## Electronic shelf labels
Walmart uses digital labels to update prices from a central computer instead of paper stickers.
## Instacart price variations
Shoppers at one Safeway in Washington, D.C. saw different prices for the same corn flakes within minutes.

> An 18-ounce box of Signature SELECT Corn Flakes appeared for $2.99, $3.49 and $3.69
## Price transparency concerns
Digital pricing risks creating price disparities without clear explanations for shoppers.
## Walmart's promise
Walmart says it won't use electronic labels to change prices based on who is shopping or time of day.
## Consumer trust
Shoppers worry algorithms might charge more based on their habits, like black beans consumption.
## Key takeaway

Walmart claims its AI won't change prices based on shoppers, but digital labels risk creating price disparities.
