The Amazon Big Spring Sale just came and went in what feels like the blink of an eye. Thousands of deals on offer and plenty of great discounts to be had over the course of a few days. With so many great buys and deep discounts, it was tough not to go overboard and add everything to your cart -- and even easier to hit "buy" and check out with all those purchases.

However, after the dust settles and you get all those packages in the mail, buyer's remorse could set in. What seemed like a great deal that you couldn't pass up is now something you actually didn't need. It's time to make a return. 

Amazon makes returning items easy but there are a few things to watch out for to avoid paying fees. Read on to learn all the things you need to be aware of to ensure your returns are free.

Provide a reason for your return, not an excuse

Be honest and precise about why you're returning the product. If possible, Amazon and third-party sellers want to resell the merchandise (like through Amazon Warehouse Deals), so they'll check your items against your justification once the package is received. 

Here are all the various return reasons Amazon gives you to choose from:

1. No longer needed: You changed your mind and don't want the item anymore.
2. Inaccurate website description: For example, the photo shows a royal blue, but the item is a light sky-blue color. Similar to, but different from, "Wrong item was sent" (see below).
3. Item defective or doesn't work: It could be broken or simply doesn't do what it's designed to do (for example, a power bank with a broken USB-C port).
4. Bought by mistake: You accidentally hit Buy Now or forgot to delete an item from your cart before checking out.
5. Better price available: You've found the same thing at Walmart, for example, for less than you paid for it at Amazon.
6. Product damaged, but shipping box OK: The box isn't dented, cut or scratched, but the item inside has cosmetic or mechanical damage.
7. Item arrived too late: The item was delivered past the guaranteed delivery and missed, for example, a birthday or holiday.
8. Missing or broken parts: Similar to "Item was defective or doesn't work" but applies specifically to the attachments or other items that come with a purchase.
9. Product and shipping box both damaged: Somewhere between being boxed up and arriving at your door the package was mishandled, and the product arrived broken.
10. The wrong item was sent: If you received a completely different item from the one ordered.
11. Received extra item I didn't buy (no refund needed): Something extra got packaged with your order, and you feel obliged to return it.
12. Didn't approve purchase: Someone, perhaps a child or friend, ordered something on your account without asking and you got charged for it.

If you order with Alexa, Amazon returns are always free

If you're considering a purchase but are really worried it won't qualify for free return shipping if it doesn't work out, order it through Alexa. Physical merchandise ordered through voice-shopping with Amazon's digital assistant always comes with free returns, regardless of the reason. The only exception is Amazon Pharmacy purchases.

To return a product purchased using Alexa, process your return as normal in the Returns Center and Amazon will automatically refund any applied shipping charges. You should see your refund within seven days of Amazon getting the merchandise back.

Look at all of the return shipping options available

When Amazon asks you to select a return shipping method, Kohl's Drop off may be the default preselected option, but it's not necessarily the one you want.

To get to the UPS Pick-up option, here's the only way to return items without leaving home:

1. Scroll down and possibly even click a link that reads something like "See more return options."
2. When you finally see the option for UPS Pick-up, it should also show the cost as $0.00 (unless you've chosen one of the few reasons for a return that Amazon charges for, in which case Amazon will deduct about $6 from your refund).
3. Tap or click UPS Pick-up and select Confirm Your Return.

Tell Amazon how you want your refund

You'll have to choose how you want to get your money back: The quickest way is to request a credit to your Amazon account, which the company will issue as soon as UPS scans your return into its system. You are then restricted to spending the money at Amazon, however.

You can also have the funds put back on your debit or credit card. But even though Amazon will issue the refund as soon as UPS takes possession of your return package, it still could take three to five business days to show up in your account. 

Whether you choose a credit or a refund, you'll still need to decide how you want to send the item back.

Pack everything up and send it back to Amazon correctly

Follow whatever instructions Amazon gives, which usually include printing out a packing slip and placing it in the package with your return. 

Tape up the box good and tight -- even over the return label so it won't get damaged -- and put the package near your front door so you won't forget to set it out on the next business day. 

You might even want to set a reminder on your phone or with Alexa or Google Assistant so you don't forget.

If you schedule a pickup but forget to leave your return outside, UPS will hopefully leave a note and attempt pickup two more times. In the worst-case scenario, the UPS driver will leave a prepaid mailing label that you'll have to apply to the package yourself, and then you'll have to cart the thing to the nearest UPS Store or UPS Dropoff location.
