I dunno, buying stuff at least gives you some emotional leverage in your simp game. pathetic open letters on facebook not to much.
one is free tho
the other requires a decent credit history
hey i'm not saying it's much better, but at least if you target your simpery towards the right woman you might get a robotic pity hj at some point down the road when her boyfriend dumps her and she comes over to spill her emotions on your lap.
it's risky to be sure, but sometimes you just gotta put all your simp cards on the table and (not ask her out like a normal person) try to buy her affections.
