One in two mothers turns to social media for shopping ideas, according to the following infographic based on a She Knows survey.

Finding coupons and deals is the number-one reason cited for using social.

Despite the coupon-hunting, "most moms start shopping for back to school about one month before school starts, and they don't set a budget," states She Knows.

The biggest expense is clothing. Most moms spend between $100 and $250 on clothes and between $50 and $100 on school supplies. They spend less than $50 on electronics.

Regarding technology, most survey respondents think kids in elementary school should have their own desktop computer, e-reader, and music device. When children are in middle school, those students should have a laptop, tablet, and smartphone, according to the respondents.
