Photo prints are on sale for 10 cents each at Target this week, a fairly nice sale.

But why pay anything at all when you can use a coupon and get 40 4x6 prints for free?

Ride Raleigh's buses for free, trade in your dish liquid or laundry detergent for an eco-friendly version, pick up a packet of flower seeds and learn how to turn your old T-shirts into high fashion.

It's all free in celebration of Earth Day.

Here's a roundup of just some of the Earth Day freebies available in the Triangle.

Head over to Target's free sample page to grab a sample of a new line of products from Seventh Generation.

The site asks for your ZIP code to see if you qualify, then you have to answer a few questions.

My Apex ZIP worked so the offer should work for most folks here in the Triangle.

Food Lion has been the place to be this week (and last) for free Yoplait yogurt. But you can also pick up free large bottles of Sun Light dish liquid and large cans of Dole Pineapple for as little as 17.5 cents each.

Here's the deal:

The Target "Sample Spot" has got a new freebie up for grabs: a small tube of a new toothpaste for kids from Tom's of Maine.

Head over to samples.target.com to sign up for a free sample of Tom's of Maine Wicked Cool Toothpaste.

Aimed at eight to 12 year olds, the toothpaste has a mild mint flavor.

The freebie will show up in your mailbox in eight to 10 weeks.

Target, which earlier this year acquired an 11-acre parcel in the Parkside Town Commons development in Cary, announced Friday that the story would open in March 2014.

The company expects to hire 200 workers for the 135,000-square-foot store. Target will host job fairs two months prior to the opening.

Taking aim at Amazon, Target has announced it will price match the online giant, as well as other online competitors, throughout the year.

The new online price-match guarantee, which Target temporarily offered during the holiday season, went into effect Tuesday, immediately after it was announced by Target corporate officials.

Shoppers will have seven days to find a lower price at Amazon, BestBuy.com, ToysRUs.com, BabiesRUs.com and Walmart.com. The guarantee also extends to Target.com.

The News & Observer's  coupon database has been updated with all of the new coupons -- and there were a bunch.

This Sunday's home-delivered Final Edition of The News & Observer contains six inserts -- three Smart Source, two Red Plum and a Target -- for a total of 302 coupons with a face value of more than $400.

That's before you double the first coupon, of course, which we have the opportunity to do every day of the week at Kroger, Harris Teeter and Lowes Foods.

And this week, we have the good fortune to take advantage of Harris Teeter's Super Double coupon promotion, which doubles coupons with a face value of up to (and including) $2. That promotion runs through midnight Tuesday.

Not familiar with the coupon database? You can access it on the right-hand side of the blog. There's a button at the bottom right to view it as a full-size page. Since there are multiple inserts, I've numbered each one and identified it in the database key.

You may also download the database as an Excel spreadsheet by clicking on the attachment at the bottom of this post.

It's a handy tool, giving you the most timely and detailed list of coupons in the Triangle.

UPDATE: Since I first wrote about Ibotta last November, the app has made big changes worthy of an update. Once exclusive to the iPhone, Ibotta is now available to Android users. And once limited to Target, Walmart and Walgreens, Ibotta users can now cash in at dozens of more retailers. In the Triangle, you're now also able to use Ibotta at CVS, Rite Aid, Kroger and the store I'm most excited about: Harris Teeter. And remember, the coolest feature of Ibotta is that you can use its digital coupons along with paper coupons to save even more.

If you want to trim your grocery budget, but don't have the time or inclination to clip coupons, you're in luck. There's now an app for that.

Called Ibotta, the iPhone app is aimed at tech-savvy bargain hunters looking to save a little cash on their supermarket purchases.

Instead of clipping paper coupons, Ibotta users collect their discounts by playing with their smartphones.

So far, three of the biggest American retailers have signed on to allow their customers to use Ibotta: Target, Walgreens and Walmart.

The discounts are similar to paper coupons -- 25 cents here and 75 cents there.

But instead of using a scissors to clip....

Target and Harris Teeter will anchor the first phase of Parkside Town Commons, a commercial and residential project planned for the intersection of O’Kelly Chapel Road and N.C. 55 in Cary.

Kite Realty, the developer behind the shopping center, announced this week that construction on the multi-phase project will begin early this year.

The 250,000-square-foot first phase, which will be anchored by Target and Harris Teeter, is scheduled to open in 2014.
