This is all in shop.java ~~

Declare this

public static int pointShop = 50;

Put this under the public boolean "is general store"

public static int[][] EctoTokenPrices = {
    {20135, 500}, //This means {itemid, value}
    {20139, 200}};

search for this

int price = getBuyPrice(item);

under that put this there

if (money != 995) {
            for (int i11 = 0; i11 < EctoTokenPrices.length; i11++) {
                pointShop = 50;
            if (item.getId() == EctoTokenPrices[i11][0]) {
                if (money < EctoTokenPrices[i11][1] * quantity) {
                player.getPackets().sendGameMessage("You need " + EctoTokenPrices[i11][1] + " Ecto-Tokens to buy this item!");
                return;
            } else
                pointShop = 50;
                player.getPackets().sendGameMessage("You have bought a " + item.getDefinitions().getName() + " from the store.");
                player.getInventory().addItem(EctoTokenPrices[i11][0], 1);
                player.getInventory().deleteItem(EctoTokenPrices[i11][1], i11);
                return;
            }
        }
    }
