personally i always went to restaurant le wow on hibernal ave with a amulet coin and my strongest pokemon paid 100,000 for a double battle meal, after a perfect battle i got 64,512 plus 25 balm mushrooms which i sold for 131,250 or else i just went and sold any x attacks x def etc and it worked pretty well so now i want to hear your ways of making alot of money in x and y

Here we go :
1. I always go to restaurant le wow in order to get some money, I mean it's so easy and you can just get so much money from it, let's not forgot how much experiance you can get from it as well.
2. I often find stuff that I don't need, unless your still playing the story mode, you might as well sell those spare burn heals you have laying around, also some items are really worth lots so it's worth it.
3. Helping out in the hotel. You can only do this once per day and it doesn't give you that much, but if you really need the money, try it
4. Battling the elite 4 again. This also gives you a good amount of money

Well I don't got time with those things you guys do I only battle the league and get some money while I'm battling them mostly like I think 10,000 dollars per person and I think the champion gives you 16,000 something in money but i'll try your things and see how they work out.

I just sell all of the random things in my bad I never use, for a bit of extra cash, and, more importantly, I go to the Restaurant Le Wow. If you win in the right amount of turns each time at the restaurant, then you can get some serious cash, fast! Also, like @DarkLord said, you can fight the Elite Four and Champion, to get about 50,000 or more each time.
