Wallet Pop reports that Coffee Mate, Seamless Web and Starbucks are all offering (separate) variations on the theme, perhaps their way of getting a leg up on the blitz of ads sure to be discussed on Monday.

Coffee Mate‘s Free Flavor Friday promotion for Facebook fans (say that 3 times fast) has been such a success that the company is adding 20,000 bottles to it’s originally planned 100,000 bottle giveaway due to technical difficulties (too many people trying to get in on the deal at once?). You still have a chance, but the giveaway was always planned to end at 11:59pm PST, or once 100,000 people accepted the offer, so click quickly.

Seamless Web, an online food ordering website that serves New York, Boston and Washington, DC restaurants (as well as one of our favorite alternatives to room service in said cities), is offering 350,000 free cups of coffee in partnership with restaurants in each city, and all you have to do is show up. That’s one reason to battle it out with winter weather.

Starbucks is probably the biggest brand name, but their free coffee offer isn’t quite as free as the others.

“Buy any 5-, 6-, 7-, 8- or 12-pack of VIA from a Starbucks or a grocery store and if you don’t like it, return it to Starbucks for a 12-ounce bag of free Starbucks House Blend ground coffee. This offer is valid for VIA purchased between Feb. 2, 2011 and Aug. 31, 2011. The taste test guarantee is good on VIA black coffee, flavored coffee, and iced coffee.” {Wallet Pop}

While a coffee exchange is nice, there’s not much of a risk for Starbucks – whatever your feelings are about the VIA instant coffee, you’ll still be drinking their coffee. Guess that’s one way to make sure the ever more minimalistic logo doesn’t mess with brand recognition in any way.

So click quickly to get your free Coffee Mate bottle, stop in to a participating Seamless Web restaurant – every day if you’d like – to get your free cup of joe, and if you’re still not hopped up enough to assure a fitting Super Bowl super buzz, stop by your local Starbucks to give a trial run to their instant coffee.

Good news! You could win one of 10,000 pairs of jeans from the Gap by going on Facebook. The social network announced Wednesday that, with the help of a forthcoming Facebook app that will be similar to Foursquare, thousands of shoppers will receive free jeans for visiting Gap stores. The first 10,000 people to “check in” on a designated day will be the winners. {Fashionista}

Privacy - increasingly difficult to find on Facebook, but look at the positive side: you'll get free jeans or 40% off in exchange!

Shoppers will have to physically be inside a Gap store to “check in,” and those who are not one of the first 10,000 but “check in” anyway will receive a 40 percent discount on a pair of Gap jeans. To put this in perspective, the Gap has just over 3,000 retail locations worldwide, so about three pairs of jeans will be given away at each store. {The Cut}

It looks like the folks at the Gap are trying to wash the logo change fiasco taste out of the publicâ€s mouth, but apparently this is just one of many forthcoming giveaways and promotions Facebook will participate in. The Web site is gearing up to launch a “deals” program, which will be very similar to Foursquareâ€s “deals” program, whereby checking in at certain businesses earns you discounts for that business.

We absolutely love hearing about all the creative ways social media is being used for business purposes, and who doesnâ€t enjoy free stuff? It is a little creepy, though, to think about people “checking in” with Facebook – much like someone would check in with their spouse or boss at various points throughout the day. Then again, it does seem as if creepy has become Facebookâ€s middle name (anyone want to create a petition to change the name to Stalkbook?).

Location based social media has also already shown security risks, with one man reporting last May that his home was burglarized when he updated Twitter while on vacation, thus announcing the vacancy of his house. {azcentral} Facebook has an insecure login process that is not helping security matters, and a new Firefox plugin has made it easy to grab user logins over insecure wi-fi connections. {Valleywag}

In short, if you’re checking into your local Gap (or anywhere else) over a free wi-fi connection, there is a good chance that the busy-looking guy sitting on the nearby bench can see your password. While it might not seem like a big deal that a stranger can access your friends list, or that you’re a fan of cheese, if you use the same password for other accounts – like your email address or online banking - it can easily become a goldmine of information for stores in addition to online criminals and pranksters.

In case you’re still too enticed by the free stuff, weâ€ll be sure to keep you updated when a date is set for the Gap giveaway.
