Shoppers can buy $5 "savings pass" to get up to 25 percent off on items — even items already on sale.
The program has raised more than $45 million for charity since 2006, the retailer reports.
You can buy the passes at Macy's or at A Little Easier Recovery, a North Andover nonprofit that aids people recovering from cancer. Nationally, proceeds from this year's event benefit the March of Dimes.
