I signed up for crowdtap simply to try it out. We are currently a single income family, so every little bit helps- and we love free samples. However, we are also private people and would very much like to remain that way. This site/sample program wants its participants to not only share personal information (to see which samples are a good fit for your family- totally understandable), but also wants said participants to flood their social networks and contacts lists with brand photos and messages in order to even APPLY to possibly have a chance at getting a sample of a certain product. Compared to other sites (ex. Pinchme), this is too much work and too time consuming for just the possibility of receiving a sample. Add to that the fact they want you to flood your social media with their partners' branding... It's a no brainier for us. If you're not a 'private' person, don't mind sharing a ton of branding and what not on your social media, and have a lot of time on your hands- then, you could give it a try. It's just simply not for us.
