Demand for iPods is surpassing expectations and available stock, according to feedback from retailers today.

High-street stores are rapidly selling out of Apple’s market-leading music player, with news breaking that even online sites such as Amazon, Best Buy and eBay are similarly struggling to satisfy consumer demand.

A spokesperson for Amazon, the world’s biggest Internet retailer, revealed it had completely run out of some models, and only had one from five of the iPod mini devices left.

Apple spokeswoman Natalie Kerris voiced public assurances that stock will be replenished in time for the Christmas run-in.

“We are making and shipping iPods as fast as we can,” she said.
