Section 470.280 Use of Terms
"Two for Price of One", "Buy One, Get One Free"
It is an unfair or deceptive act
for a seller to state or imply that products are being offered at the usual
price of a smaller number of the same or a different product (for example,
"Four pillows for the price of three" or "buy one pair of shoes,
second pair free") unless:
a) The seller clearly and conspicuously discloses all material
conditions which are imposed on the sale; and
b) The price indicated by the seller as its usual and customary
price for the smaller number of products is the sellers' own former (regular)
price for such products as determined in accordance with Section 470.220 of
this Part.
