Buy It Now! Research on Impulse Buying and Ecommerce

This is a summary of articles found during cursory Internet searches regarding impulse buying and ecommerce.

A more attractive printable version is posted here at Docstoc.

Most of these are “newbie” articles because I lack marketing experience. This list has been filtered in based on quality. Star ratings ranging from 1 to 3 indicate perceived quality.

Most articles found were user-generated content, and focused on the topic of “how to avoid impulse buying.” They severely outnumbered explanations of how to induce impulsive shopping, so it appears that the retailers are winning, and the consumers feel relatively unable to resist. Only one of this type of is included as an example.

Impulse buying is defined as anything from a purchase that wasn't planned, to a purchase that someone felt compelled to buy, but felt regret or guilt about later. Impulse buying accounts for a significant fraction of sales, both in brick-and-mortar and online retail, ranging from around 20% to 40% of all purchases.

Impulse buying in brick-and-mortar stores is different from impulse buying online, as expected, but what they both have in common is “browsing”. Impulse purchases are made when a product is displayed to the shopper. While it is obvious that a shopper won't buy something he cannot see, both traditional and online stores often fail to design the floorplan or web-page to let the customer see more products as they look for what's on their shopping list. The “take away” point is that browsing environments must be created, planned, and maintained to encourage impulse buys.

Additional factors affect impulse shopping, but ecommerce web-sites are still relatively primitive, and they aren't all browseable yet.

Articles summaries and a list of articles follows.


How to Prevent Online Impulse Shopping *

http://www.howtodothings.com/hobbies/how-to-prevent-online-impulse-shopping

  • Know your priorities.
  • Don't be distracted by sales.
  • Never use credit cards unless necessary.
  • Don't rationalize purchases.
  • Make a budget.
  • Don't be swayed by advertisements.
  • Get support – don't shop when you're down.

This article was kind of lame. How do you avoid using credit cards online? Also, online is actually not that good for impulse buys because there's no “there” there. I include it here only to give an example of a typical article trying to help people deal with impulsive shopping.

My tips for reducing online impulse shopping.

  • Keep bookmarks for online vendors who don't try to up-sell you with too many “related items”.
  • On Ebay, Etsy, Half, Buy and Amazon, keep lists of favorite vendors in your bookmarks. (They try to make this a challenge.)
  • Research purchases. This consumes time, and can feel good. The trade off is that you'll end up buying something eventually.
  • Feel happy before going shopping.

The Impulse Buy ***

http://www.newsweek.com/2007/08/13/the-impulse-buy.html

Everyone feels guilty after an impulse buy, but people who are less likely to buy impulsively feel guilty about it twice as long. Impulse buyers felt guilt, but by the next day, felt good. The more prudent buyers were more likely to follow up their impulse with a practical decision. This decision is not conscious.

Why People Buy Green ***

http://www.ecofriendlymag.com/general-green-news/why-people-buy-green-for-many-its-impulse-and-curiousity/

“Light green” shoppers, who make up 89% of the market, buy green items out of curiosity. “Dark green” make up only 9%, and do research before purchasing. 39% of light greens made the purchase decision at the store, versus 20% of dark greens. 15% of light greens were motivated by learning about the product, versus 29% of dark greens. (The writing in the article is convoluted.)

Impulse buys are purchased more often by the younger and older buyers, and they pay $27 for the game (compared to $42 for planned purchases). 43% of buyers said they paid $10 to $20 for the game. Lower prices induce impulse shopping.

Impulse Toy Purchases *

http://www.almightydad.com/behavior/impulse-toy-purchases-the-outrageous-cost-of-tiny-toys

This is a funny article worth reading for entertainment value. He says, “they play on our parental insecurities and they know that cost is not going to prevent us from purchasing our children’s happiness...” I suspect what they also get parents to purchase toys that they would want for themselves.

http://www.mequoda.com/articles/membership-websites/3-impulse-buy-tactics-for-membership-websites-to-use-in-the-holiday-season/

  • Give the customer something to print out. This is something a person can gift to someone else.

  • Set a price for the gift-giver, not the recipient. It's the only time you can drop membership costs without upsetting existing members.

  • Make the website look nice – it reflects on the gift giver. Web visitors judge a site in the first 10 seconds.

On the Negative Effects of E-Commerce: A Sociocognitive Exploration of Unregulated On-line Buying ***

http://jcmc.indiana.edu/vol6/issue3/larose.html

An older paper from around 2001 by Dr. Robert LaRose, who specializes in media and telecommunications. This doesn't discuss ecommerce as much as psychological factors like addiction, compulsive behavior, and shopping. The ecommerce part seems dated.

What causes customers to buy on impulse? **

http://www.uie.com/publications/whitepapers/ImpulseBuying.pdf

2002 paper by User Interface Engineering. I think it's results are distorted by the fact the participants were given money. Shoppers think of things to buy as they shop. 87% of money spent on impulse purchases resulted from category navigation. The other 13% were from using search. Site searches narrow focus too much. Well designed navigation exposes customers to more products, resulting in more impulse buys.
