Trade is one way of balancing your budget. It"s a good way to trade with your unused things but be careful with your old things. Make sure that it is still usable. I have a friend who wants to trade but don"t want to do this via ebay or amazon. I don"t know why. Maybe the connection is so slow or simply he wants to do it directly to traders.
Doing this personally is okay. Look for your friend who has an interest or friend of your friends. If not, then go to the market and say "I"m trading for whatsoever!" These are some ideas good to trade and have your own dream nerf gun. That"s what I do and it"s effective.
Other than that, you can visit different villages or for sale stores where it can help you. Some people are ashamed to do this. But hey! It"s not about what people say. If you really want something, you"ll do everything. Just keep in mind that you want to get something from your own good ways and exerted lots of effort. Again, that"s just what I always do.
Lastly, use the new media, internet.
"http://nerfhaven.com/
"http://nerfhq.com/
"http://nerfgunsforsale.org/
"http://www.tradekey.com/
These are the four sites where you can get trading. Here, lots of people buy and sell nerf guns plus many more.
Choose any of these ways of what you want to use for trading. It"s depending on how big your confidence is. Or choose the best way where you can trade faster. Always do what makes seem easy for you.
