For the fourth -- and final -- week in a row, Kroger is offering customers a coupon for a free product through its digital coupon program.

Today, Feb. 8, you will be able to load a coupon for a free 2 liter of Pepsi Next to your Kroger loyalty card.

The coupon is only available on Feb. 8 but you have until Feb. 23 to redeem it.

Today's digital freebie is the final one in what Kroger Mid-Atlantic spokesman Carl York described as a four-week test to "jump start what we're doing digitally."

York said there will likely be future freebies -- and more digital coupons overall -- but "we want to take a breath and measure it to get some feedback from customers."

"We're going to put more and more coupons out there to drive people to our site," he said.

If you've never added digital coupons to your Kroger loyalty card, it's easy to do.
