It sounds easy, really is, to check pricing of a product to sell if its profitable. Just need some commonsense. Yet many do mistake in this.

After you get the wholesale price list from your prospective supplier, find out how much others are selling for that exact same item.

Some good places to check pricing:

• Ebay.com
• Amazon.com
• Overstock.com
• Walmart.com

Many people selling on these sites (except walmart) are suppliers. Since its very competitive there prices are lower there. You really have to make sure you are able to compete with those sellers there.

Your sell price should consist of these parts:

• wholesale price
• shipping cost (if you offer free shipping)
• listing/success fees (if you sale on ebay/amazon etc where you have to pay for listing/success)
• Operational costs (this could be hosting, office supplies etc)
• Marketing expenses (marketing costs like ppc etc)

Based on this see how many percentage of profit you can make per product. If you make less then 25% profit, I would strongly recommend looking for some other supplier.
