surprised no one mentioned this yet but all the above r good ideas xD
yes, as TryTheTrick said u gota work hard to earn money (unless someones dropping heaps on sb or watever XD)
but anyway... u could also try selling syrups (mainly Grape, Mango, Cantaloupe etc.)
it may take quite a bit of time but by the end of a week or month u will have gained soo much profit xD
goodluck ^^
