Looking hind-site, after spending close to $100 so far at QI. I'm actually not feeling that bad. Initially, when I first spent my first $40ish (or so), I was feeling really PO'd(angry). However, considering there are so many LN's that are basically free. And finding hidden gem LN's that only cost 4 coins per chapter. Plus the LN's that are being purely translated out of fandom (aka free completely). So all of this combined, I'm feeling really happy with all of this reading material. You could spend years reading on QI and not have to spend $100 like I did (just to catch up to were I'm at).
Anyhoot, love ya QI. You're still overpriced as heck, but considering so much free chapters. It's actually not that bad.
P.S. Until you expand your money grubbing ways. SHANK YOU!
