Kangaroo Express RooCups are back. And I've got four of them up for grabs for lucky readers.

Leave a comment or question at the bottom of this post, and you'll be entered to win one of the cups, which will come in handy as the weather heats up.

The cups are your ticket to 25-cent refills on soda and slushies -- all summer long -- at any of the more than 1,570 Kangaroo Express locations in the Southeast.

If you don't want to take your chances on winning, you can reserve a RooCup now on the Kangaroo Express Facebook page. Reserved cups will be ready for pick up starting at noon on April 24. They sell for $6.99, plus tax.

If you don't reserve a cup, you'll be able to purchase them starting on May 1.

The 25-cent soda and slushie deal will be honored through Labor Day.

Similar to last year, Kangaroo Express also has several RooCup promotions in the works.

Sign up for text messages about in-store deals and free refill days by texting “ROOCUP” to “843766.”

New this year is a Kangaroo Express app that will tell you the closest place to get a refill and give you access to coupons and deals. Download it for the iPhone, Android or Blackberry.

You have until noon Friday, April 26, to enter the giveaway. One entry per person. I'll announce the winners on the blog later that day.

Good news for owners of Kangaroo Express Roo Cups.

The summerlong promotion that allows folks to refill their cups with soda or slushies for 25 cents has been extended.

The deal is now good through Sept. 30.
