It is really 25% off not 33%.

3 items at normal price X .25 = 75% of the normal price

3 items at normal price X .333 = 99.9% of the normal price (call it
100%)

Therefore the first three are really at 33% off making the 4th one
"free".



Of course I guess you could look at it another way. They are giving you
all
four at 25% off. Guess it works both ways.


It doesn't work both ways. I think the problem is that you think "Buy 3
and
get one free" indicates that the deal applies to 3 rolls of insulation.
It
applies to 4.

A 33% discount is what you get if you buy two and get one free (for a
total
of 3).
A 25% discount is what you get if you buy 3 and get one free (for a total
of
4).
A 20% discount is what you get if you buy 4 and get one free (for a total
of
5).

If you buy 16 rolls at $32/roll and then get a 33% discount (we'll skip
sales tax for now), you should be charged $341.33.

If you were to buy 12 rolls at $32/roll (and got 4 free as advertised),
you'd be charged $384.

If you were to buy 16 rolls at $32/roll and then got a 25% discount on the
lot of them, you'd also pay $384, which works out to $24/roll.

With sales tax, you should have paid $407.04 for the 16 rolls you had on
the
cart, which works out to $25.44/roll. Lowe's was right. You were not
cheated.


Actually, after rereading the original post, I have determined that Jack got
a better deal than he may think. If the original price was $38/roll, Jack
should have paid $28.50 per roll, for a total of $456. The confusion comes
from the $32 price tag. Either way, Jack got the best possible price.
Lowe's gave Jack the advertised discount off the sticker price on the
insulation. Had he received the discount off of the price in the computer,
he would have paid a total of $483.36. Paying attention to the difference
between the sticker price and the computer price saved Jack $76.32. Lowe's
did right by Jack, but only after he spoke up.
