quickly as possible. Evidence indicates that Microsoft launched with all consoles available at the time, and was operating at maximum production capability (that is, they did not withhold produced consoles). They did not, however, build up a sufficient supply of consoles to satisfy the entire demand at launch. This allowed them to launch several months earlier than would otherwise be possible, but also led to shortages. Immediately after the launch, reports about the new machine's technical glitches started coming out. Some reported the Xbox 360 crashing with errors, some reported the hard drive does not respond in certain situations while others report error messages during various games or unusually fast overheating. Due to the issues caused by overheating of the first consoles, Microsoft extended the Xbox 360 warranty by 3 years, which cost more than 1 billion US dollars. The manual contains warnings about not placing the Xbox 360 on soft surfaces or in enclosed spaces to avoid heating problems. Microsoft claims that these problems are to be expected on a large scale release for a console and the number of reports versus the number of consoles released was minimal. Microsoft stated that they would look into the reports and offered assistance reachable by phone. The high demand for the Xbox 360 led to some owners almost immediately re-selling their console for vastly increased prices. eBay in particular was a popular location for such offers with thousands of consoles going up for auction, some selling for many times the original retail price. It was reported that 40,000 units appeared on eBay during the initial month of release, which would mean that 10% of the total supply was resold. According to the NDP Group, North American sales totaled 326,000 units in November. In Canada, all 32,100 units available for launch were sold. By the end of 2005, Microsoft stated it sold roughly 23,000 units. As of January 1, 2008, the Xbox 360 has sold 9.15 million units in the US. Analysts believe Microsoft did not meet the original worldwide target of 2.75–3 million units sold in the first 90 days after launch, and Microsoft revised their initial 90-day estimate down to 2.5 million units, though their 6-month sales estimate remained unchanged at 4.5 to 5.5 million consoles. The Xbox 360 was released in Mexico on February 2, 2006. Retailers such as Liverpool, Wal-Mart, Blockbuster, Sam's Club, CompuDabo, Game Planet, gdGames and
