It could also be that he was using a variant of the "Bait and Switch" ploy:
Advertise one item a low price to attract customers into the store
and try to sell another item when they come in.

Another Bait and Switch ploy works as follows:
        1)  Salesman talks customer into buying brand X, usually
            a reputable brand.
        2)  Salesman goes to stock room, ostensibly to get desired item,
            but returns with brand Z, saying the famous line
                "We just ran out of brand X, but we have brand Z,
                WHICH IS MADE AT THE SAME FACTORY AS BRAND X."
Never fall for this line (or similar ones).  It is almost aways a lie.
Almost invariably, the markup is higher on Z.
