A Cape Cod woman got an extra bonus with the bunch of grapes she bought from a local supermarket -- a black widow spider.

Laurie Kaiser of Yarmouth said she been grabbing a handful of grapes off the bunch stored in the refrigerator for about a week when on Wednesday she noticed a spider.

She tells the Cape Cod Times at first she was going to let the spider go in her yard, when she saw the telltale red hourglass shape on the spider's body indicating that it was a black widow. Black widows are venomous, but rarely fatal to humans.

The Shaw's supermarket gave her a refund and the manager said he'd inform the distributor about the spider.
