1. Thorough market research is the foundation for success

Meticulous market research doubles your chances of making a tidy profit from the wholesale goods you buy. Start off with a list of 5-10 different ideas. Then check completed listings searches on eBay to see what the item generally sells for and the sell-through rate for each one. Use Yahoo's free keyword tool http://inventory.overture.com to find out how many people are searching Yahoo for your product per month. You can double this figure for Google. Add the numbers together. If there are ten thousand or more searches per month for an item, this indicates a healthy market.

2. Calculate the REAL cost of your item

One big reason why people fail at the wholesale game is that they don't do the numbers. In other words, they don't treat wholesale like a real business. To accurately discover your true profit potential on an item, you need to add the shipping cost and insurance, eBay fees (or equivalent for other advertising), Paypal and/or credit card fees (these can be a real profit killer), packaging costs and labor involved packaging, and any storage costs to the cost of your item.

3. Verify ALL suppliers found on the Internet

Getting caught out by scammers is a common stumbling block for people new to wholesale. If you are searching for suppliers off your own bat (rather than using a wholesale directory like SaleHoo), it is CRITICAL to check authenticity before making a purchase.

Always take the time to:

• Check that the website gives a full business name and a registration number.
• Check for a legitimate contact telephone number - this will involve ringing the number. Do not accept a mobile phone number alone. All real companies should have a land line number.
• Go to http://www.whois.sc/ and search for the name of the website. A legitimate company will have a domain expiration date in several years time. Most legitimate companies reserve their domain names for 3-5 years or more at a time.
• AVOID suppliers who won't agree to use secure payment methods such as Escrow.com, Credit Card and Paypal Verified.
• Still uncertain? Ask other sellers what their experiences have been with the company you are interested in on eBay forums.

4. Chinese suppliers give the competitive edge

Chinese suppliers are an essential source for anyone wishing to make money selling online. Manufacturing costs are currently extremely low in China, thus it is the secret to gaining a competitive edge. Dealing with China does have risks, but these can be alleviated if you place a small order first, use secure payment methods, get shipping insurance for 110% of the cost of the items, and use suppliers with a good reputation

5. A common stumbling block for liquidation and closeout

Always obtain the reasons for liquidation and closeout sales before you buy. Liquidation and Closeout sales can be a fantastic source for cheap products, but you usually have to buy by the pallet load and these can sometimes include broken or returned goods that aren't in sale able condition. To be safe, ask specifically whether broken items and returns are included before you buy.
