- eBay.co.uk is of course THE biggest online auction site in the UK, and is a great source of income if you sell consistently. Is 100% safe, and with ebay now owning PayPal, everything works seamlessly together, sellers and buyers have their respective protection policies to help protect should anything go wrong with a transaction.

The only downside we have found with ebay is probably the fees they charge. All sites inevitably want to make money but with ebay you will get charged 3 times:

1) Listing fees for listing your item in the first place, which will vary on the value of the item you are selling. Remember, you will get charged this whether you sell your item or not.
2) Then if you do sell your item you will be charged what is called a FVF (Final Value Fee) which is a percentage taken from the final selling price of your item, again the % will be dependant on what format you have listed your item with and of course the final selling price.
3) If you have used Paypal as your payment processor (which most people do nowadays unless you have agreed to accept cheque or postal order) you are inevitably charged the Paypal receiving fee.

These 3 fees put together can mount up, so before you put anything on ebay make sure you account for these fees, and if necessary add them on to your initial starting price.

Also, don't forget to add up your postage and packing charges before you list your item. There is no point in weighing your items afterwards only to find that you haven't charged enough postage, which will then eat into any profit you have earned. Always weigh your items and work out a reasonable packaging charge BEFORE you list, then you can display this in your listing and everyone knows where they stand.

All in all though, ebay is a pretty good way to earn some cash, as long as you take everything into account.
