Rite Aid Corp. said today it plans to sell $800 million worth of debt securities in two batches.

One sale will be for $300 million of 10-year notes; the other will be for $500 million of eight-year notes.

The Camp Hill drugstore chain said it would use the proceeds to redeem existing notes that were to mature in 2011. Those securities, paying 91/2 percent interest, total $300 million. Funds from the new sale also will replenish an existing credit line.

The sale's lead manager is Citigroup.

Rite Aid operates 3,300 stores in 27 states and the District of Columbia. Its shares were down 7 cents to $6.23 in morning trading on the New York Stock Exchange.
