I'm a disappointment to my savings account... (Should I buy it? )

Holy... I’ve been spending way too much on merch lately. I’ve already dropped like 200k+ IDR, which might sound small in dollars (like $13-15), but for a student in my country, that’s actually a LOT of money *tears*. My country's currency is crying and so am I. and there’s still more I want to buy, the temptation is just too strong... I mean, it's a CHRIS REDFIELD'S CHEST poster?! And the worst part is, it’s limited!! If I don't grab it now, it’ll just go 'poof' and disappear forever unless the artist decides to restock next year... which is a big maybe.

So, should I just grab it now and go on a strict 'financial diet' afterward? or should I be a responsible student and let it go? (but it’s Chris...) Someone please tell me how to stop spending my moneyyyyy! or just tell me if this poster is worth the sacrifice...
