Retailers large and small can have sales on Super Saturday, the last Saturday before Christmas. Get ready to shop or pick up store orders to get discounted gifts on hand by the holidays.

You can usually cancel an order that hasn’t been processed or shipped and get a full refund. But even if you miss the cancellation period, you can probably return the item after it arrives.

Many retailers have extended their vacation return policies. However, some articles or categories may be excluded. For example, Macy’s has a 90-day return window for most items, but a 14-day window for Apple products and tech accessories.

Check retailer websites for policy details. Read the fine print carefully to make sure you understand the terms and deadlines.

Take a 14 day return policy, for example. “Does that mean the day he leaves their warehouse?” Is this when the 14 day return window begins to run? Is that the day he leaves there, or is that the day he shows up at your door? Thomas said.

You will also need to be very careful with things like whether you can return the item to the store instead of sending it back, and whether you will be refunded to the original payment method or store credit. If something isn’t clear, call the retailer or use the online chat feature to ask questions, Thomas says.
