Students and parents are getting ready for the first day of classes.

This weekend marks one of the biggest for back to school shopping.

Some states are even giving parents a break with a tax free holiday.

But Colorado parents aren't so lucky and the cost of going back to school is going up.

According to the National Retail Federation's back to school survey, the average person with children in kindergarten through 12th grade will spend nearly $700 on their kids, that's up $85 dollars last year.

We got our hands on one school supply list and went shopping for the same items twice, first online and then in a big box store

Ezschoolsupples.com turned out to be a one stop shop.

We bought everything from the from the Orchard Elementary fourth grade list from the web site.

Without shipping, the total cost was over $60.

Then we took the list to Target, where we found many of the exact same items.

We saved about $10 shopping for the supplies in person.

The National Retail Federation says shopping online for school supplies in a growing trend.

Survey shows four in ten people will shop on the internet for school supplies this year.

Those who do will spend 27% more than someone shopping in stores.

The NRF says the average family will spend $688 dollars on supplies this year, if they go online they'll spend $874.

Total K-12 spending is expected to reach over $30 billion.
