CHICAGO (CBS) — Are your fingers and keyboards ready? This coming weekend may be a time to stay home to shop online.

CBS 2’s Dorothy Tucker explains why deals will be better than they were on Black Friday.

Kem Morah was browsing at Sears on Thursday. She said she plans to do her real Christmas shopping this weekend online, hoping to find better deals.

“In this economy, I have two kids that want everything and I’m trying to fill their Christmas stockings; so, yes, savings is a plus,” Morah said.

Shoppers like Morah will save big by waiting. According to Chris Garlotta, co-founder of Zingsale, consumers will save an average of 42 percent this weekend, compared to Black Friday when the savings averaged 34 percent.

“Stores know that this is the last weekend that shoppers are going to be out for Christmas and they’re offering lot of savings and most are offering free shipping,” Garlotta said.

You’ll find savings in almost every category. HDTV’s that were discounted 25% on Black Friday are 34% cheaper this weekend. Digital Cameras, a 25% savings before will be a better buy at 31% discount. Popular tablets were just 16% off on Black Friday; this weekend they’ll be about 25% off. You would have saved 39% on video games on Black Friday, now you’ll save 46%. And winter clothing was sold at a 38% savings on Black Friday, but will be a super bargain at 52% off this weekend.

In addition, on Friday, some 2,000 merchants are offering free shipping with a guarantee you’ll get your gifts before Christmas, although some of them have minimum purchase limits to qualify.

If you miss the Friday deadline, you’ll still be able to find some stores, like Sears, that promise free shipping on select items if you order by Sunday, Dec. 18.
