Customers say Pepsi and Walmart schemed to raise prices at every store except the big box retailer

PepsiCo and Walmart illegally conspired to fix the prices of Pepsi soft drinks, so they were lower at Walmart and higher at other retailers, according to a new class action lawsuit filed by consumers.

The complaint, filed last month in federal court in New York by lead plaintiff Martin Gelbspan, alleges the two major companies broke numerous laws, including state antitrust laws; the 1890 Sherman Antitrust Act, which outlaws monopolies and secret restrictions on competition; and the common law doctrine of unjust enrichment, which outlaws unfairly benefiting from another party’s expense.
