I agree with Jason, after myself working for more than twenty years in photographic retailing, a price is just an invitation to make an offer, in fact the computerized tills we had in recent years after entering the product code for an item would tell the staff the ticket price and the minimum price it could be sold for to still make a profit, and with second hand equipment there was even more leeway , so my advice would be, do you're shopping on a wet Tuesday when business is slow, and make them an offer.
