Another good way to save money is to be very frugal with your earnings. Custom heads and bodies can be refunded quickly and easily for full price within the first hour of uploading. Any later, you only receive half. I recommend coming to a hasteful decision as soon as possible. Because when the sooner you decide to refund, the better, and the more time you have to correct the head.
For furniture and homes you should sell as little furniture as possible. By selling your furniture you're actually losing more money than gaining it. If you have both a house and guild house use this to your advantage by having your house as storage to prevent wasting your furniture and to also accumulate more wealth with a house farm. This is also a very great way to keep all your exotic limited edition furniture and put everything to use. Unless you truly do not need the furniture item at all, I strongly advise you to keep all of your earnings. Who knows? You may find a use for it when you decide to redecorate.
Other items and hats should only be purchased if you are absolutely sure you I'll use and wear them. There's a hat preview function for a reason, use it. Also try to avoid spending on recolors and similar hats unless you are positively sure you will wear them. Same for items. Do you really need so many kinds of juggles and pogos?
Never, ever, ever. buy bombs and arrows when you can easily kill baddies for free. The only reason you should need to buy them is for towering or PKing. Never farming or anything else. Because if you farm constantly while buying bombs you'll learn that 90 bombs costs about 90 gralats and with the speed it takes for gralats to grow, you're losing out on more money than you think. House Vendors should only be used for PKing and towering so that you and your guild can easily stock up on ammution quickly instead of wasting time on Baddies. For a farmer trying to earn money; however, you should spend the least amount of money as you can.
