* Fixed Price listing. This is where you have many of the same item for sale. You will list the total number of items and the price for each of them. Buyers can buy however many they want at the set price. This is good for the buyer because they don't have to wait for an auction to end. The seller must be ID verified to sell in this manner. If they are not, then their feedback rating must be above 30 and they need to have been registered for at least 14 days. Or if you have a Paypal account and accept Paypal as the means of payment, then you need only have a feedback rating of 15.
* Lot listing. This is where you sell say a case of similar things to the one buyer. For example a set of 10 records in a collection that you want to sell for an average of $10 per record. To sell items as a 'lot' you click on the 'lot' tab in the quantity section. Then fill out the details by entering the digit '1' in the 'number of lots' box and in the number of items box you list how many items are in the collection, eg, 10. You the set the price at $100.00. The winning bidder will take all the items.
* Online auction-type listing. This works almost the same way as an ordinary on-line auction. The items are listed with the total number of items and the starting price. This is what the seller would like for each item. The buyers then bid with the number of items they would like to purchase along with their price. The highest bid price per item is one that wins, but the buyer does not have to accept the items unless he can get the number he actually wants.
Sellers are limited to 10 lots of multiple listing to prevent one seller from dominating the eBay marketplace and to make it fairer for other sellers. The seller is not to use multiple seller ID's to get around this rule, or he will risk cancellation of his listing, account suspension and other unpleasant effects. The exceptions are only for tickets and vehicle light bulbs where you are allowed to have 20 for the former and 25 for the latter running simultaneously.
