1. You don't use it often
It's liberating not to have to think about paying shipping fees. If you're the type of person who places Amazon orders as soon as you notice you need something -- resulting in multiple deliveries per week -- then it's clear you're getting a good value for your $119 a year.
Some people, however, have more ordering discipline. They make lists and ponder whether to buy something online or in-store, placing fewer digital orders, but larger ones. That type of shopper might only want to pay for Prime if they order multiple times per month.
If you order less than that, you should consider other benefits in the package. For example, if you order once or twice a month, but watch Prime Video regularly or shop at Whole Foods often, you're probably still getting a good value.

2. Walmart could replace it for you
Walmart(NYSE: WMT) offers free two-day shipping on qualifying orders over $35, without requiring any sort of membership fee. Its selection is much smaller than Amazon's -- a few million items compared to over 100 million -- but that may not matter to you.
Figuring out whether Walmart can replace Prime for you requires doing a test. Attempt to make a switch to see if either the $35 threshold or the selection causes you problems. You may find that with some minor substitutions, Walmart's free service works well enough without being too much of a sacrifice.

3. Your ordering habits have changed
Back when Prime launched in 2005, books and CDs were still big sellers. Now, many consumers have switched to digital solutions for books and music. That may have changed how often you order shipments from Amazon without you really noticing.

If you're not buying household items from Amazon -- such as groceries, toiletries, or cleaning products -- you may not be taking regular advantage of the free shipping. It's also possible that you have switched some of your ordering to other services like Instacart, Target's same-day delivery offering, or even Walmart's curbside pickup.
