Most of us receive hundreds of emailed receipts each year. The team behind Shoeboxed.com, a startup based in Durham, North Carolina, promises a way to safely store them. Anyone can sign up for the free service. Once enrolled, users receive an email address which they can give to merchants when buying online. The receipts then go to their Shoeboxed mailbox, where they’re safely stored. Better yet, the service allows members to organize their receipts by creating virtual shoeboxes, for a recent vacation or a series of tax-deductible home-office purchases, for example. Result: no more hunting for receipts in shoeboxes of the cardboard variety, or in a regular email inbox. Shoeboxed recently added a feature that allows users to scan in paper receipts for storage on the site.
