Something unique that MyPoints offers that most other similar companies don't offer is the ability to earn cash back on some in-store purchases at select stores, along with their online paid surveys. Also, although their online store cashback rates aren't the highest in the industry (ironically, Swagbucks beats them on several offers), they do have special offers that other companies don't have, such as a bonus to sign up for Amazon Prime.
When companies want to better focus their marketing, advertising, and product development efforts, they will contract with a market research firm to target their ideal demographic (for example, men between the ages of 40-60 who play golf), and gather information about consumers’ opinions on their product or service.

Survey Club has been offering online paid surveys since 2005, and in the fast paced every changing world of the web that’s a reassuringly long amount of time. They are a bit of an acquired taste, in that they specialise in long, detailed surveys for high end clients rather than the quick and cheerful consumer surveys that you may be more familiar with. Whilst this does mean that you may have to commit a bit more time, it does mean that if you have the patience to persevere with them they pay more money than most survey and reward sites. They also offer local taste tests (see what I said about ‘an acquired taste’?), and secret shopper opportunities.
