Make the most of big retailer sales days.

Whether you’re a big online shopper or not, you’ve probably been bombarded with ads promoting retailers’ annual online sales events. While the multi-day occasions promise huge savings and exclusive discounts, the sheer volume of “deals” can be overwhelming, and consumers can wind up spending more than they bargained for on items they don’t actually need. Here’s a guide to help you shop wisely, ensure you're getting the best deals, and avoid unnecessary purchases.

• 1. First, make a list and stick to it.

• In some ways, the big sales events can feel like a casino, or like Black Friday felt back in the days before the internet. Retailers create the impression of a frenzy where time isn’t on your side, which can fluster even the most seasoned online shoppers. To avoid the adrenaline rush, create a list of items you need in advance.

• 2. Next, do your research.

• Once you know what you’re planning to purchase, research both reviews and current prices at multiple retailers to find the exact model you’d like, and bookmark that items’ page at each retailer that may be price-matching. It may be worth creating a spreadsheet with links so that you’re not wading through searches trying to find your exact item during the sale.

• 3. Take advantage of free trials.

Some sales events are only available to members who pay to get access to exclusive deals, free shipping and other perks. The good news is that most sites offer free trials for such services. Be sure to read the fine print before signing up, and remember to cancel the trial within the allotted “free” period if you decide not to continue with the service.

• 4. Set a budget and don’t exceed it.

Decide how much you’re willing to spend during the sale and stick to it. This financial discipline ensures you don’t overspend and helps you prioritize essential purchases over impulse buys.

• 5. As always, price shop.

The day of the big event, use price comparison tools and websites and the list of links you created to check the current prices of items across different retailers — the biggest online retailers may match or beat each other’s prices. Some websites track price histories of items over time, allowing you to see if the sale price is genuinely a bargain or just a marketing tactic.

• 6. Take advantage of cash back and rewards programs.

Maximize your savings by using credit cards that offer cash back or reward points for purchases. Just ensure you’re paying off your balances in full each month, or you’ll wind up wiping out any savings you might have gained in interest payments. You can also utilize cash back websites or apps for extra savings.

• 7. Beware of flash or lightning deals.

Some retailers offer limited-time “flash deals” or “lightning deals” that offer an item at a significant discount for a short period or until stock runs out. Beware: just like the check-out line at the grocery store, these are often impulse purchases that weren’t on your list and that you can live without. All the more reason to keep your list of links handy — so you can avoid having to virtually walk down the sale or candy aisle on your way to check out! You can also set up alerts for specific items, and in some cases, retailers may even allow you to sign up to be “invited” to certain deals.

• 8. Check return policies.

Before making a purchase, review the retailer’s return policy to ensure that you can return items easily if they don’t meet your expectations or if you change your mind. A good return policy adds an extra layer of security to your shopping, allowing you to buy with confidence.

• 9. Keep a cool head.

Big sales events are designed to create a sense of urgency and encourage impulsive buying. Don’t let the flash sales, countdown timers, and limited stock warnings fluster you into making purchases you weren’t intending. Stay calm and think critically about each purchase. With intention, you can save a bundle.
