hi, we work with smartadserver and we would need someone with an e-commerce of any kind to place a post impression pixel during 1-2 days in order to test if this pixel works. it's just for testing if a banner that we will place in a web site is seen, and then the user buys anything in the ecommerce, if that pixel will report the amount that has been bought. we need to check that it works before implementing a bigger campaign for a client. thanks.
