Price gouging and war profiteering are as American as, um, apple pie (English origin, actually, or so they say), not that they (price gouging etc.) don’t exist worldwide as well – and neither requires a war. Sigh.
“If you have been charged an excessive price for a product or service under normal circumstances, please file a complaint with the Attorney General’s Consumer Protection Hotline by calling 503-378-8442, or using the online Consumer Complaint Form.” [Link to webpage.]
Visit the Oregon Department of Justice, Attorney General Consumer Protection Hotline website for more information.
For what it’s worth: there is also anti-price gouging federal legislation in the works.
