Customer Demand
Section 470
Section 470.310 Customer
Demand
It is an unfair or deceptive act
for a seller to advertise any product for sale when the seller does not have
that product in stock in sufficient quantities to meet reasonably anticipated
customer demand during the effective period of the advertisement, except where:
a) The seller clearly and conspicuously discloses in its
advertisement that quantities are limited or that restrictions apply to the
advertised offer; or
b) Conditions beyond the seller's control (i.e. bankruptcy of
source, labor stoppage, Act of God, etc.) interrupted the supply of the
product; or
c) The seller has, in good faith, ordered the product in adequate
time for delivery and in sufficient quantity to satisfy reasonably anticipated
consumer demand, and the seller has maintained sufficient records to
substantiate such orders; or
d) The seller tenders a raincheck entitling prospective
purchasers to buy the advertised product at the advertised price and redeems
the raincheck within a reasonable time after the issuance thereof; or
e) The seller offers prospective customers a product of an equal
or greater value at the same price which is acceptable to a reasonable consumer
or is of a lesser value at the same dollar or percentage savings.
