If you can't return an unwanted item, it can end up costing you money instead of saving it. That's why it helps to know which stores have the easiest return policies. Good Housekeeping has put together a list.
Costco, gives you a long window -- up to 90 days -- to return electronics. And they have no time limits on returning other items.
At CVS, you can return store-brand products for a full refund, even if they've been opened, as long as the receipt.
And they're even more lenient for cosmetic, where the same policy applies to even items that aren't CVS brand.
Kohl's return policy is as simple as it gets -- they'll take back any product, at any time, for any reason.
And Zappos, the online shoe retailer, even gives you free shipping if you have to send back shoes that don't fit.
