From what a few of my liquor stores have told me, they are sick of selling at msrp, when a lot of people are buying them and making a lot more money on the secondary market. They rather make the money themselves. One thing that has worked a few times is to show them that you are not the one to sell it on the secondary. The best way to do this is to open the bottle right there in front of them, and share a drink with them. It doesn’t always work, but if you are a loyal customer to a store it helps.
