Do you suffer from Allergies? Right now you can get a free 7 day trial of Zyrtec by filling out a two question survey here: StartSampling.com
Depending on your answers, you may get a $2 coupon or the sample. I imagine you get the sample only if you answer a brand other than Zyrtec because they would like non users to try this brand. If you use it than $2 is still a great deal too!
