These online retail storefronts are open to anyone -- individual or corporate giant with goods to sell -- at a bargain-basement listing price of $9.99 a month for up to 3,000 items, or just a dime each for single items. Amazon also takes a small percentage of the actual selling price, scaled from 5% for items priced less than $25, to 2.5% for items costing $29 to $999, down to 1.25% for items more than $1,000.
