This article focuses on consumer perceptions of transaction value when pres
ented with deals that are equivalent on a unit-cost basis but worded differ
ently. Through an experimental design setting, it examines the effect of th
ree such frames: one, stated in terms of a straight price promotion ("50% o
ff"), the second, as an extra-product or volume promotion ("buy one, get on
e free"), and a third as a "mixed" promotion ("buy two, get 50% off"). Four
typical supermarket categories are considered which permit the investigati
on of the effect of two category-based moderating factors: stock-up charact
eristic and price level. Results show that the nature of framing appears to
differentially affect consumer perceptions of value from "equivalent" deal
s. Also, perceptions of deal value from price versus extra-product promotio
ns are moderated by the stock-up characteristic of the category. However, c
onsumers' internal reference prices remain unaffected across one-time price
and extra-product promotions. These findings provide some understanding of
the role of deal framing on consumers' responses, and offer implications f
or industry practitioners interested in communicating the maximum value in
their deals. (C) 2000 John Wiley & Sons, Inc.
