Well, I complete almost all paid offers on the site.
Those that offer trials.
You have to keep the subscription for at least 7 days tho.
I also really purchased some products that I find acceptable such as sending flowers to my girlfriend.
I used virtual credit cards on sites that sound sketchy such as geek, freester or etc. I also do research on the company’s cancellation policy or frauds before I signed up for the trial. There are some sites you really want to avoid.
Hope that helps!
Should be able to get you 2k+ credits.
