https://www.amazon.com/samplesPrime Samples is a new program that allows Prime members to try samples of products. You can purchase a wide variety of samples, with prices ranging between $2 and $4. For each sample you buy, you will receive a credit equal to the price you paid for the sample. Your credits can be used toward a future purchase of select full-size products from the category you sampled. For example, if you purchase a shampoo sample for $2, you’ll receive a $2 credit that can be used toward a future shampoo purchase.
