New York, New York -
(NBC News) Back to school shopping is a $72 billion industry, which is why some stores have gotten an early jump on sales this summer.
A downward change in the economy is behind a National Retail Federation finding that one in five families actually plan to spend less this year, which explains why competition among retailers has already heated up.
Experts say, however, that while prices have been low, your best chance to get the best back to school sales might end this weekend.
"This is really the weekend...the crowds are going to start to gather in August, the deals are going to change," said Dan DiClerico a Senior Editor for Consumer Reports.
