Please note: ALL contests are now banned from Neopets. Please do not read this article (even though it is quite good).
1.) Get a good rare item (neggs, faeries, p/bs, etc.)
2.) Get a lot of misc. items
3.) Price them fairly to the nearest hundred.
4.) Price the rare item(s) at 99999np (just incase someone does buy it.)
5.) Now, in your shop description tell the people something like, “1st place gets the rare item!!” or something. Make it fair by making it a drawing contest. (ex. 100np= 1 ticket.) If you want to, make a date as to when the contest ends. Don’t tell them that you are trying to obtain a certain item, as they will think it’s a scam. Also never make a contest that says something like, ” I will tell you a secret if…” and so on.
