Some online return policies can be hard to find, difficult to understand and involve paying extra fees. Visit the company's web site and carefully review its return policy. If it's not listed, call or send an e-mail to the company to request specifics.
Many sites have time limits for returns.
In most cases, you can stop the clock by notifying the company by e-mail and letting them know that a return is on the way. Print or save the e-mail message and any responses you may receive. Expect to pay some fees. Companies that have web-only businesses typically do charge customers a restocking fee or shipping and handling fee on returned merchandise. If you're a long-time customer or purchased the item using the merchant's credit card, mention that fact and ask for a waiver of the fees.
