If you are looking out for free samples of any of the product, then you should be knowing when and where you could get the free stuff. One possible way to know about this would be to go directly to the retail shop and check if at all they are providing any free samples of their product. But this is a time consuming option and if you need to check out with many retailers, then it is going to take a lot of time and energy. There is yet another way to know these details and that is through internet. Now, almost all the retailers have their own websites in which they are providing all the necessary details to their customers. They would have listed all the products they sell, sometimes their prices and most importantly they list all the promotional offers provided by their retail shop. So, with these details you could very easily trace which retailer is providing free samples of the product you are looking out for. In many cases you could directly register for the free sample in the website and they will deliver to your home and in many other cases you have to personally visit the retailer to get the free stuff. If you have the required details on hand then going to the retailer would be a one time job.
