Amazon Prime Day can be divisive. Some Prime members can't wait for the event, and others feel like it's just a big garage sale. Before Amazon celebrates its fourth annual Prime Day, we surveyed DealNews readers to understand their feelings about the shopping holiday. After almost 1,500 responses, it's clear that most shoppers are feeling unsure about all things Prime these days. Read on to learn the biggest findings from our Amazon Prime Day survey. Amazon Prime Day Is Growing In last year's survey, 48% of our readers said they shopped the 2016 Prime Day sale. That amount jumped to 66% for the 2017 event. We'd typically expect similar results for this year's sale. However, 49% of those who shopped the 2017 event said they're either unsure about checking out Prime Day in 2018, or they definitely won't shop it. Half of those who shopped the 2017 event said they're either unsure about checking out Prime Day in 2018, or they definitely won't shop it. As for the 34% who didn't shop Prime Day 2017, 28% gave "didn't think the deals were good" as the reason they didn't shop. Moreover, for both Prime Day 2016 and 2017, 29% of non-shoppers said they simply didn't know about the event. A whopping 20% of respondents have already decided they definitely aren't clicking over to Prime Day this year. Why? Most said they believe the deals aren't good. Prime Day Is Big for Electronics Fans For those planning to shop Prime Day 2018, electronics is once again the most popular category. In 2017, 26% of respondents were planning to shop for electronics, followed by 13% planning to pick up home goods, and 12% who were unsure of what categories they'd shop. This year, 28% are planning to shop for electronics. And again, 12% of our readers have no idea what they're going to shop for on Prime Day. SEE ALSO: When Is Amazon Prime Day 2018? Consumers Are Interested in Competing Sales With the popularity of Prime Day growing over the last few years, other retailers have started offering competing sales. This year, 45% of our survey respondents said they're planning to shop these other sales. Additionally, 44% said they aren't sure whether they'll shop the sales offered by other retailers. Still, many shoppers seem interested in what other retailers will be offering that day. As consumers eye competing sales and shop Prime Day with no clear goal in mind, it appears the invented holiday is becoming its own event. Alexa Shoppers Are Increasing Only 8% of last year's survey respondents said they redeemed an Alexa-only deal during Prime Day 2016. For Prime Day 2017, that number grew to 20%. While the majority of shoppers still aren't excited to buy Alexa-only deals for Prime Day, the fact that there was a substantial increase suggests these deals could get more prominent. Only 8% of last year's respondents said they redeemed an Alexa-only deal during Prime Day 2016. For the 2017 event, that number grew to 20%. We should also note that in recent months, Amazon has done away with its page showcasing Alexa deals. Instead, the mega-retailer has focused on marketing that displays ways to voice-shop with Alexa. This leaves shoppers with only one option, which is to ask Alexa what her deals are, sit through a litany of descriptions, and then tell her they do or do not want to buy the items. These technical hassles may be a problem if you're competing to add a short-lived lightning deal to your cart on Prime Day. Prime Members Love Free 2-Day Shipping Prime includes a variety of benefits for its members, but according to our survey, that free 2-day shipping is the classic perk members love the most. The next three most-loved benefits were Prime Video, Prime Music, and Audible Channels. A Quarter of Prime Members Won't Renew With the recent price increase for Amazon Prime subscriptions, it should come as no surprise that members are feeling sticker shock. A quarter of our survey respondents are already planning to skip renewal — and nearly a third are unsure if they will continue their subscription. For some, this year's Prime Day could be a deciding factor on whether the new $119 price tag is worth it. Readers, are you planning to shop Prime Day or its competing sales?
