If you've ever used PayPal to buy anything you owe it to yourself to read this story at CNN Money. Next month, eBay and PayPal will begin holding payments sent through PayPal for up to 21 days for certain "high-risk transactions."

Furious at the prospect of waiting to receive funds, sellers have been publicly speculating about how much money PayPal (and its parent company, eBay) makes off the accruing interest on funds under PayPal's control - and whether a desire to retain those funds for longer spurred eBay's holding plan. However, company executives and industry analysts say the money PayPal makes off such payments has a negligible impact on its bottom line. Any funds PayPal holds for dispersal are automatically deposited in a corporate bank account, which earns interest, according to Paypal representative Amanda Pires. The money is kept there until it's ready for distribution. PayPal, which processes payments for eBay auctions as well as e-commerce transactions from elsewhere on the Internet, counts interest payments on those funds as one of its revenue streams.
