CHICAGO (Reuters) - Retailers posted better-than-expected sales in August as consumers sought out bargains during the key back-to-school selling season.

Early reports gave analysts hope retailers were able to clear excess inventories ahead of the crucial holiday-selling season without having to resort to deep discounts.

But with stubbornly high unemployment and weak consumer sentiment, shoppers were still focused on low prices when choosing what to buy.

"The cheaper it is, the more I go there," Jialing Jiang, a Chicago high school student said on Wednesday as she shopped on the city's State Street.

Nine of the 11 retailers that reported as of early Thursday morning beat analysts' expectations, according to Thomson Reuters data.

"Discounting was particularly heavy this back-to-school season, and early," Ken Perkins, president of Research firm Retail Metrics, said.

Analysts also said the warmest August in more than a quarter of a century helped spur sales of late lingering summer clothing inventory.

The month was the warmest since 1983 and second warmest in 50 years, according to Planalytics Inc, which provides weather information to businesses.
