I'd try asking again with correct use of grammar and punctuation so people know what the hell you're asking.
If I can understand you, you're asking what to do with an offer that you've been told about.
This offer is for a free trial of what would normally be a retail product, and is not listed as a CPA offer, but rather as a per sale offer, if I understand correctly.
Logically it's still a "sale", as the stupid customer will be forking money over, hand over fist, once the free trial is over. Hence, they've been "sold" to.
If it pays well, and it converts well, go for it.
If it doesn't, go and take some English Writing courses.
