Shoppers wait outside Sears in Braintree, Mass., as Black Friday 2012 begins.

Bumping Black Friday one day earlier just wasn't enough.

Sears and Kmart announced Wednesday that they will kick off their Black Friday deals one week ahead of time for their "Shop Your Way" rewards customers to compensate for the shortened holiday calendar.

Sears' online shoppers will be able to buy 1,000 reduced items starting Friday, Nov. 22, at 8 p.m. Kmart's website will offer 100 items on Sunday, Nov. 24, at 1 a.m.

"Giving early access to Black Friday doorbusters is the ultimate holiday shopping perk," said Imran Jooma, president of e-commerce at Sears Holdings, which owns both companies.

The news comes as myriad retailers are pushing their Black Friday deals forward to stay competitive, particularly with six fewer days between Thanksgiving and Christmas.

On Tuesday, Wal-Mart Stores announced that it would kick off Black Friday sales at 6 p.m. Thanksgiving Day, two hours earlier than last year. A growing list of retailers—including Macy's, Target and Best Buy—have announced they will be open Thanksgiving.

Sears allowed its Shop Your Way members access to online sales five days early last year. This is the first year Kmart will participate.
