Aldi grocery chain is investigating after a family discovered a spider baked into a vanilla wafer cookie.

Eric Sowa found the arachnid in the cookie last Thursday. When the family complained to Aldi about the find, they were offered a $5 coupon and told the manufacturer would contact them.

Sowa called the coupon laughable, according to WABC-TV.

Aldi called it an "isolated incident."

The grocery chain told WABC-TV:

"At ALDI, we take the safety and integrity of the products we sell very seriously. That's why every private-label food product we sell comes with the ALDI Double Guarantee, which means we will replace the product and refund the purchase price of any ALDI food product if a customer is not 100 percent satisfied.
