Free food samples are available at local grocery stores and restaurants. Store websites and freebie sites also list free samples that come through the mail.
Most grocery stores put out free samples during peak shopping periods to encourage shoppers to buy featured products. The membership store Costco is renowned for having free food samples during all its business hours. Likewise, other stores such as Safeway, King Soopers and Wal-Mart encourage customers to join their free club by offering free products periodically. Walmart.com and Target.com also list free samples on a daily basis, often related to food.
Freebie websites are a likely resource for free food samples through the mail. As of 2015, SampleBuddy.com lists categories of free food samples available through the mail, including cereal, chocolate, coffee, tea and candy. Typically such sites curate the free samples from the parent sites. For instance, some of the offers listed on the site require downloading a coupon to a club card or downloading the store's application to a smartphone.
A slightly different freebie website is StartSampling.com. The site requires signing up for a free membership. Likewise, members have to complete surveys to earn their free samples. Coupons for free products are also available on the website. The site also has a frequent-tryer program that allows members to accrue points to use toward prizes such as tote bags and T-shirts.
