Under California BPC §17500, advertising a "former price" is illegal unless that price was the prevailing market price within the last three months, or unless the date when the alleged former price did prevail is clearly, exactly, and conspicuously stated in the advertisement.
EU - This is the most critical component. Any time a retailer announces a price reduction (e.g., using a strike-through price like "~~$98.00~~ $59.99"), they must display the "prior price".
What is the "prior price"? It is defined as the lowest price the retailer applied for that specific product for at least 30 days before the current price reduction.

If your "Compare at" price hasn't been active in the past 90 days, you are at risk of violating California's BPC §17500.
