Thinking About Bl

I heard someone say Im Jessica?? Who the hell is Jessica? The jessica girl who slept with mr wilson

So i have like 8 dollars worth of money in my amazon acc (gift cards) so basically i need help with figuring out what to do >~< I want to buy the movie doukyuusei/classmates but its 9.99 to buy and it's 3.99 to rent (digital on amazon) the problem is that i don't have enough money to buy the movie but i do have enough money to rent it. I would rent it if I didn't want to rewatch it but spending money on something only to keep it for a month kinda sucks T^T I wanna keep it forever yk... So my question is should I just save up a little bit of money and keep it forever or should I just rent it and regret it later on? Please help <3333 Personally i think i should wait and save up a bit more!
