Return To Sender -- Please! Woman Accidentally Mails $3,200

HACIENDA HEIGHTS (CBS) — We've all put a letter in the mailbox without a stamp...or the wrong address...or maybe you forgot to seal the envelope and all the contents of your letter got lost along the way.

But when it comes to all-time mail gaffes, Anjelica Castaneda might win the prize. Hands down.

The money's in the mail...literally. And it shouldn't be!

Castaneda accidentally mailed $3,200, in cash, in a bank deposit envelope last Friday when she mailed some bills at the corner of Green Drive and Gale Avenue in Hacienda Heights.

She had been saving up for new dentures..."they can be pretty expensive," Castaneda says. And the pair she has now doesn't fit, they're uncomfortable and they hurt. But after discovering her mistake, more than her teeth ached.

Castaneda didn't discover her big blunder until the next day...making tracing the envelope that much more difficult.

A Wal-Mart greeter by trade, Castaneda had been saving up for some time. And as KCAL9's Ann Sterling reports, Castaneda is incredibly embarrassed. "How could I be so dumb?" she said, with a sigh.

She's hoping someone will come forward and return her hard-earned dough but if not, she's ready to start saving all over again. "I will save up again," she says, "if that's what I have to do."
