If something goes on sale after you bought it, don’t kick yourself. You won’t necessarily have to eat the cost of your inopportune timing.

Here are some options for getting money back.

• If you spot a lower price within a few weeks of purchase, you’ll often be able to get the difference refunded by going directly to the retailer.

Target, Kohl’s, Macy’s, Walmart and Best Buy are a few stores that offer price adjustments.

While some retailers match competitors’ prices before purchase and only their own prices afterward, Target will match select competitors’ prices up to 14 days after you buy.

Keep your receipts handy in case the store requires them.

If you made your purchase online, make note of your order number before contacting the retailer.

• Or try Paribus, an app that monitors price reductions and sends price adjustment requests to retailers on your behalf.

• For travel purchases, it pays to make a phone call.

For instance, if hotel room rates change before your stay, you can ring the front desk and ask to have your bill adjusted to the new, lower rate.

• Or cancel your reservation and book again if prices drop — as long as you’re within the cancellation window, won’t face a fee and haven’t prepaid, says Rick Seaney, CEO and founder of travel website FareCompare.

Always read the fine print.

• Credit cards offer another approach to getting a refund through price protection.

If your card has this feature, you’ll usually need to register items after you buy them with the card, then submit a claim form if you notice a price drop.

For instance, Discover cardholders can file a claim to get back up to $500 on eligible items if they find a lower price within 90 days of purchase.
