Many deodorant companies offer free samples, including Dove, Secret, Degree and AXE. Check each companies' website to learn the specific requirements to obtain free samples.
Sign up to a product testing site, like SheSpeaks, BzzAgent or Vocalpoint, to receive sample offers. Most product testing sites require participants to fill out surveys. Based on these results, you receive products to test and rate. Companies like Dove and Secret partner with these companies to gain feedback when they are about to launch a new product, or they are trying to make improvements on a pre-existing one.
As of 2015, Walmart gives away free product samples on its website and in stores. Usually, Walmart provides its customers coupons they can exchange for a free product. Additionally, many free sample websites, like Free Stuff Times, Sample A Day and I Love Free Things, list links to daily free samples. Subscribe to these sites to receive emails that may include information on when deodorant samples are being given away.
The most effective way to find free deodorant samples is to subscribe to your favorite deodorant brands' email lists or follow them on social media. These brands often announce free sample giveaways. Supplies may be limited.
