It was a tough August for teen apparel retailers, as many reported weakness across some or all of their product categories during the critical back-to-school season.

Teen retailer The Buckle Inc. said Thursday its same-store sales rose 22.4 percent in August.

Retailers, including Wal-Mart Stores, are posting solid same-store sales growth in June, as expected, as seasonal weather and tax rebate checks helped get consumers to the store.

Consumers stepped up their shopping in May after the tax rebate checks hit bank accounts, giving many of the nation's retailers a boost and helping them to top analyst estimates.
