Amazon.com has taken cautious steps toward selling groceries online - one of the best known examples of the dot-com bust's casualties, reports Reuters. The new service is limited to nonperishable goods, including pasta, cereal and canned goods, which Amazon can ship to customers. Groceries were quietly introduced to the Amazon site on May 25 in beta. "Because we only carry products when we can offer great prices and free shipping, we don't carry everything (yet!)," the company said in a notice on its site.

"We try and offer our customers one-destination shopping where they can find everything they need, and groceries are something our customers have been asking for," Amazon spokeswoman Tracy Ogden is quoted as saying. "As with any of our stores, we are always looking to increase our selection."
