Already a devoted online shopper, 34-year-old office worker Yumiko Tamagawa is finding even more reasons to shop from home thanks to the recession.

For a range of items from T-shirts to books — even beef for a home barbecue party — she checks shopping and auction Web sites for the lowest prices.

"If I go out shopping and try to compare prices at each shop, the transportation costs are too high," she said. "Web sites can show you the lowest prices instantly."
