The Better Business Bureau warns parents to be cautious when looking for baby formula. The BBB shared these signs of a potential online purchase scam: No indication of a brick-and-mortar address or the address shows on a Google map as a parking lot, residence, or unrelated business than what they list on the website. Watch for misspellings, grammatical errors, or another descriptive language inconsistent with the product. The seller advertises on a social media site and is communicative only until you make payment.
