Great Product Testing and WOM Site I've Joined
BzzAgent.com - I've been an active BzzAgent since 2009 and have received 13 BzzKit Campaigns (Clean&Clear, Burt's Bee's, Children's Claritin, and more) as well as numerous online Campaigns. Sometimes it does take some time to get into campaigns, but once you do it is worth it. Just keep up to date on all surveys and activities.
Vocalpoint.com - I've just joined Vocalpoint this year, however I have received multiple 'Try&Tell' products (including a full size bottle of coffee creamer). Like other sites you have to qualify for most of the product testings, however they also have free sample that anyone can get.
Smiley360.com - Just found this site a month ago and have already qualified for and received a full sizes product (BIC Soliel Bella Razors). This site is one of the easiest to navigate so far and the shipping time was amazing.
Expotv.com - Joined this site just this week and today I qualified for my first product (Febreeze candles). The only down side I have seen so far is that all reviews are submitted via video, so if you don't have a way to take videos I'm not sure how far you'll get on this site.
SheSpeaks.com - I'm brand new to this site and haven't seen any products I might be eligible for yet, but I was told that this was a favorite site for a fellow BzzAgent. I will let you know how it goes.
