Dear IMakeVeltVids,
There are no free trials apart from special promotions / weekends. Currently there is a promotion, but it is a summer sale to get Premium 25 % cheaper. When this sale ends there is always the chance of the free premium weekend coming back. Meanwhile you can use the free cheat or check out the premium cheat which will cost you 25 % less for the next few days. There will be free trials soon, but I cant tell you exactly when its happening again.
Best Regards,
Tqyo
