If you are in a really low low budget, there are a lot of companies out there that will send you free samples in exchange of reviews and some social media love. Here is a list of some of the services I have tried recently (with some potential affiliated links).
Once a month, they have a Sample Day (which usually falls around the second Tuesday of each month), in which some free samples are offered based on a combination of your profile and the needs from the sample providers. Since April 2016, I’ve managed to consistently get at least one sample a month, with some good months and some not so good months. The good part is that it includes samples of all kinds (from beauty samples to household products). Sometimes boxes take a little long to arrive (I just received my sample from October, and the November box is still in transit). You can also get selected for “product trials”, in which some brands will send you a full size for you to test and review.
Some previous reviews:
This service is new, but the idea is to offer one box of free samples every season. Currently, they are (still) shipping the Fall box. This first box was great, and you can see my review here.
This is another website that promises a box of free samples every season. What I liked about it is that you can choose exactly which samples you will be getting – that way, you can avoid receiving those weird samples you will end up not using. I still need to post my review of my first SampleSource box.
In this site, you are a brand agent and may receive products for test purposes. You qualify by answering surveys and raising your BzzScore. I have been using it for months now, and all I could manage to get was a sample for Vicks Sinex Severe Ultra Fine Mist – which is a great product by the way, but not nearly as exciting as the other samples people seem to be getting from them.
In Crowdtap, you join “crowds” associated to certain topics or brands. You can participate in activities related to those crowds, and eventually may apply to test a sample. So far, I only received one sample (for Zicam Cold Remedy Nasal Swabs). But the good part is that you can earn points for participating in the activities, and exchange those points for Amazon gift cards – that way, you end up getting something, even when you don’t qualify for a sample.
Influenster is totally based on your influence on social media. You can review products and participate on activities. The more you participate, the higher your chances of qualifying to receive a VoxBox. Each VoxBox comes with a combination of products. My first VoxBox was filled with food products (review here), and I have a second one on the way with a hair product (more about it soon). As far as I know, it is relatively easy to get your first couple of boxes after joining, but the thing gets really hard overtime.
