Web Coupons Tell Stores More Than You Realize

Hugh Pickens writes "The NY Times reports that a new breed of coupon, printed from the Internet or sent to mobile phones, look standard, but their bar codes can be loaded with a startling amount of data, including identification about the customer, Internet address, Facebook page information, and even the search terms the customer used to find the coupon in the first place. The coupons can, in some cases, be tracked not just to an anonymous shopper but to an identifiable person: a retailer could know that Amy Smith printed a 15-percent-off coupon after searching for appliance discounts at Ebates.com on Friday at 1:30 pm and redeemed it later that afternoon at the store. Using coupons also lets the retailers get around Google hurdles. Google allows its search advertisers to see reports on which keywords are working well as a whole but not on how each person is responding to each slogan. That alarms some privacy advocates. Companies can 'offer you, perhaps, less desirable products than they offer me, or offer you the same product as they offer me but at a higher price,' said Ed Mierzwinski, consumer program director for the United States Public Interest Research Group, which has asked the Federal Trade Commission for tighter rules on online advertising. 'There really have been no rules set up for this ecosystem.'"

      Yeah - store cards suck. But they are much more limited in scope than these coupons.

Also, if the store can track your purchase habits, then they can track your return habits as well. In the end, you may just end up paying a premium for items in a store because you are more likely to bring that item back if you have trouble with it. You may even end up with a custom-tailored warranty on things you buy as well. As far as groceries go, imagine you buy the same 10 items every week. With a per-person tracking system, the store can raise the price of those things when you buy them, but offer the same item to a lesser price to the rest of the public.

      Yes, it's definitely something we are careful about. We added the loyalty program in 2004 but we always had certain customers that we thought were PITA's based on their habits (in with sale flyers, complaining about prices, seemed to return items more frequently). Once we actually were tracking our customers then I was able to look at their shopping pattern over a two or three year period. Some were actually very good customers and just "high maintenance". They shopped with coupons, but they also shopped without and generated decent gross margin (35% is OK, 40% or higher is quite good). I made a point of alerting my staff about some of these customers that we assumed were "bad customers".

      But others were regular abusers of the program. They would buy the $25 minimum to redeem a coupon, then return most of the items a week or two later. Over a two year period they averaged less than 20% margin, some even approaching negative margin (and gross margin is only calculated on the goods and not the cost of labor, lights, rent, etc.). So these customers were truly costing me money with every trip.

      I'd say we have only about thirty of these customers in a database of 25,000 so it's a tiny percentage. They are just highly noticeable since they are high maintenance.

      Also, it's pretty difficult for them to tell that they are "low value" since they don't know about the offer they never received. They still get the basic reward ($10 for every $250 spent) but they just don't get some of the special offers.

Different people get different advertising packages, and it's already based on your purchases since mail-order places tend to share mailing lists as an extra revenue stream.

    So it's the new old thing again. Different prices to different people is exactly how the market works today - you buy something for full price, or wait until it's on sale, or wait until you have a coupon, or wait until it's on clearance. You choose the price by choosing when/how to buy.

    I'd like to point out that there's no difference between this model and ordering online - online they have your name and IP address and the link you clicked to get to their store along with google keywords if you clicked from google. All this does is expand the same idea into physical stores like fast food that otherwise would be anonymous. If you pay cash, which since more and more places are starting to accept debit/credit cards means you're already giving them more information.

Like affinity cards, coupons on the internet are an exchange for information that can be monetized. Perhaps affinity are slightly more honest, but the concept is the same. The consumer chooses to buy at one location or one brand over another because they will receive a discount. Perhaps the discount make them feel special, or allows them to buy in a location or brand they could not normally afford. In many cases there an alternative that is a comparable price without the discount. The choice is made.

    Making coupons more honest is not likely to reduce the flow of information. That requires convincing people that privacy is worth more than a bag of potato chips.
