If you come across new products at the grocery store and/or on the internet, you can purchase those products and then write a review.
If the company provides free sample, then you can send for a free sample. You can also call the company and tell them that you are a new product reviews for.....Let's say you write for a blog or web content provider or freelancer.
Ask if you can receive a sample of the product. If not you can buy the product and write several reviews from several websites. Of course you would have to write the reviews differently. However, the money that you make writing these reviews can repay for the cost of the product.
Review products like food products that are not very expensive. For the more expensive product review they must be products that you already want to purchase, such as new software, for example.
Keep a new products notebook. Send for samples where possible. Buy the least expensive new products, and the more expensive new products if you want those products yourself.
Write reviews for the online market.
Also, do research for print newspapers and magazines that are interested in new product reviews.
Some of these might be interested in reprinting your reviews from the online market.
You can also post reviews on your own "Google Adsense" blog which also earns your money. You would have to apply for a Publishers Account with Google Adsense.
In addition you can post new product reviews with Reviewstream.
New products can also be books and movies.
Whenever you buy a new book and/or see a new movie, including new TV movies, you can write a review.
