Stores often time will negotiate lower prices of certain products. However, it usually comes with compromises from both ends. Sometimes it means, pushing a certain product so the sales rap for the company they bought it from can get increased sales, while also providing a lower price for another product.
I am in the nightclub industry, take Jameson for instance, we wanted to get it for a lower price, so we call the rep they come in and sit down we hammer out the details. Bingo, the next day Jameson fliers and banners and posters are everywhere, their drinks are now a "feature" at our bar and anytime someone orders a whiskey it's always suggested they order Jameson by the Bartenders.
This happens in a lot of industries, they may be trying to push as Flower said old inventory on a customer they may think is a one or two time customer.
I faced this same what I now consider insulting behavior when I first started out. Thankfully I have a Local Reef Club and forums like these that helped me save a lot of money.
Best way to beat your spouse is to provide facts, otherwise it's just opinions...
I've had to tell mine several time, no, it makes for an strange ride back home, but I know that what's best for the tank and she will make impulse buys for "pretty colors"
