A delightful book by E. Barbeau opens with this example:
How to get drunk and rich at the same time
The column Money angles: where else to invest? by Andrew Tobias in the May 17, 1993, issue of Time offers this advice for improving your financial worth:
Buy staples in bulk when they're on sale ... Consider a family that buys one bottle of wine each week. With the 10% discount many stores offer on wine by the case, they would be saving 10% every twelve weeks - more than 40% a year, tax free and largely risk free.
One can in fact do better; increase your consumption to one case per month and save 120% over a year, thus qualifying for a 20% payback from the merchant. (Submitted by Larry Zeitel of Loras College in Dubuque, IA.)
