If you are would-be seller of eBay, there are certain things you must know. While selling on eBay has tremendous profit potential, it's important to play by the rules in order to enjoy a long association with the numero-uno auction site in the world. Ebay does not take too kindly to sellers who go against the rules and regulations of eBay and at times, even ban such sellers permanently. So, do some homework before you go ahead with your business plan. Know what's expected from you as a registered seller on eBay. Though you can sell almost everything on eBay, there are certain items that are strictly prohibited and you must avoid them at all costs. Let me elaborate on some of the items that can spoil your relations with EBay if you offer them on sale in your eBay listings.

Copyright infringement is something that's just not tolerated by the eBay folks so stay away from knock offs of music, movies, or popular TV shows if you don't want to land up in prison. Also forget those "bootleg" movies that are made by guys who secretly record newly released movies in theaters and then sell them at incredibly low prices. Similarly, sale of computer games and software that's copied is also not approved by eBay.

The "replica" market is flourishing by the day, as people buy duplicate products of popular brands. Although such products are widely sold in physical stores, forget selling duplicate handbags, or replicas of designer sunglasses through your eBay listings.

There are countless sellers out there who simply love to steal copyrighted stuff of other sellers and sell them on their own listings. Thankfully, eBay has something called as VERO (Verified Rights Owner) to deal with such offending auctions. But the sad part is that such sellers are not penalized!

Forget offering alcoholic beverages in your eBay listings or else you will be in "big" trouble with eBay. Needless to say, items such as cigars, cigarettes, and smokeless tobacco are also a strict no-no when it comes to eBay. Not even coupons for these items will be tolerated! Check out with eBay for rules regarding sale of such items.

Since sale of firearms is controlled by US law, you are not allowed to sell them on eBay. Also prohibited are satellite and cable TV descramblers and the Federal Trade Commission has stringent rules and regulations regarding the same.

And lastly, don't even think of selling animals and wildlife products! So sale of pelts and stuffed birds is out of question? Although limited sale of animal related products such as tortoise shell, ivory, and variety of marine products is found on eBay, I strongly recommend that you double check the laws regarding sale of such items.
