This one would be a good one for the late Andy Rooney.
Ever notice that while coupons are bigger in value, they also require you to purchase more than one of the item? For example, in the past, Kellogg’s might have issued coupons for 50 cents off a box of Rice Krispies, but now the coupon is for $1 off two boxes.
This hurts consumers in two ways: one, it forces them to buy more of the product than they might otherwise need (and in the process, leave less to spend on other items at the grocery store) and two, while a 50 cent coupon would be doubled or tripled, the dollar coupon would not be eligible for doubling or tripling, being redeemed at face value.
It seems to be that if makers of food and other items sold at grocery and general merchandise stores want us to buy their products, they’d make it easy to do this with small coupons on single items–rather than force us to buy more, as is the case now, and end up driving away customers.
About libertarianmathprof
I'm a college Math Professor, and have been since 2002 after teaching HS Math for a year. I teach mostly entry level subjects such as Prealgebra and Algebra, but enjoy teaching classes that have logic or statistics as part of the content (something that goes beyond just doing arithmetic). Prior to that, I worked for 25 years as an actuary specializing in the design and administration of retirement plans for small businesses.
My interests include, in no particular order:
Libertarian politics
Economics, particularly Austrian economics and political economics
Female acoustic singer-songwriters, the more unknown, the better
Oldies from the pre-British invasion era, when pop music radio stations played everything from Jimmy Dean to Buddy Holly to Johnny Cash to Lawrence Welk, and it sounded all so natural together (and you can actually understand the words as you sing along with the songs word for word)
Puzzles, particularly logic-based puzzles such as Sudukos
NPR
Will Short's puzzle on WESUN
Baseball, the St. Louis Cardinals in particular
The Cleveland Browns of the 1960's (led by QB Frank Ryan, perhaps the only NFL player with a Ph.D. in Mathematics)
The NCAA men's basketball tournament
The Winter Olympics
Burmese opposition leader Aung San Suu Kyi, the most famous person you've never heard of. Her nonviolent and tireless pursuit of democracy for Burma (and don't call it Myanmar as long as those nutcases with OCD continue their illegal rule of this nation) makes her one of the true heroes of our time--and perhaps of all time. You go girl!
When in the car, if I'm not listening to CD's, I listen to:
WFAE ("Your NPR News Source")--Charlotte's NPR affiliate. Mostly during the NPR news shows during drive time
WNCW--eclectic music legend out of Western North Carolina. WNCW plays just about anything--what it doesn't play is easier to describe than what it does play
WSGE--"your independent music source" from Gaston College. Exists in a parallel universe and overlaps a lot with WNCW.
WRBK ("Classic Oldies")--automated noncommercial FM station out of Chester County, SC whose playlist is about as broad as you can get (1950's through the early 1980's) unless it's.....
WAIZ ("63 Big Ways") a recreation of the legendary Charlotte top 40 station from the 60's airing out of Hickory, NC. Usually infested with static, but the static is a minor inconvenience to be able to hear oldies ignored by most other radio stations.
WAVO, from Rock Hill, SC. Does for standards what Big Ways does for pre-British invasion oldies. Also WAVO and Big Ways overlap a lot, with both playing some of the greatest music ever recorded that doesn't get played too many places!
650 AM WSM ("The Legend") when I'm driving home late at night after teaching night classes. The station that made the Grand Ole Opry Famous
KMOX from St. Louis. Flagship station for the St. Louis Cardinals. That says it all!
