Extended Cyber Monday at the Shop ends at midnight

Cyber Monday marked the biggest day ever for online retailers, with sales skyrocketing 30 percent over the same day last year. That same enthusiasm continues at the MLB.com Shop, where fans are taking advantage of the extended sale to buy one item and take half off another of equal or lesser value through 11:59 p.m. ET on Tuesday.

Want to know how to use that savings for your holiday shopping? Let's take a look at the most popular items sold on Monday at the MLB.com Shop.

1. Giants fans are reveling in their glory. The top three sellers are ways to celebrate another title. In order, buyers went for the Club House T-shirt, the Legacy of Champions Hood and the A&E Home Video Giants 2012 World Series Collector's DVD Set.

2. The next two items that weren't Giants goodies involved the Cardinals' new "St. Louis" look for 2013. First is the Replica 2013 Alternate Jersey, then Yadier Molina's No. 4 Replica Alternate Jersey. Note: The current buy-one-get-one sale does not apply to those new jerseys.

3. It's never a surprise when the Yankees show up high on the Shop's "hottest sellers" list. We'll list their top two sellers here; both seem appropriate given the snow in New York on Tuesday: the Authentic Triple Peak Premier Jacket and the Men's Custom Hooded Sweatshirt.

4. Though Tigers fans would like a World Series do-over, they are still going wild over their team at the Shop. They come in right behind Yankees buyers, led by sales of the Authentic Triple Peak Premier Jacket and the 2012 Property Of Playoff Hooded Sweatshirt.

5. Everyone seems to want the Astros' new look. Leading the way on Cyber Monday was the club's Authentic Cool Base BP Jersey. You'll see that around the American League cages next season.

6. D-backs fans were busy creating their own Men's Custom Hooded Sweatshirts. And as long as they bought another item of at least the same value, they were doing so for only $25, or half off the usual price for that item.

7. What will Mike Trout do for an encore? Sell a lot of No. 27 stuff. Angels fans are reeling in the Youth Replica Mike Trout Player Jersey from Majestic Athletic. Not far behind that was his Name and Number T-shirt.

8. Red Sox Nation, it looks like you are in good hands. The Red Sox Youth Replica Home Jersey was Boston's top-seller on Cyber Monday, ready to be customized any way a parent desires.

9. How about another Chipper Jones farewell tribute? The Braves No. 10 Replica Home Jersey made the list again.

10. Washington led the Majors in wins during the regular season, and Cyber Monday reflected that success. Leading the way is their Authentic Triple Peak Premier Jacket, followed by Bryce Harper's Youth Replica Jersey and Replica Alternate 1 Red Jersey.

Shipping deadlines will be just around the corner, and we'll keep you updated on key dates along the way. And remember: When in doubt, online gift certificates and MLB.com Gift Cards are safe bets for any fan.
