For me: I buy about 8 armoured neggs a day, which is about 200k.
I train my pet twice a day at the training thinger, for about 50-60k.
I do dailies and spend about 10k.
I spend about 600k solely on purchasing the items from the main shops
I usually spend about 1 mil on my gallery per week.
So what are your expenses? Do you always paint your pets? Do you collect a lot of lab maps? Is your asshole neopet making you buy it nice things? Are you trying to get all the avies, or read a lot of books?
Or do you not spend any NP and just sell it?
