wines.. make sure u buy ahead of time!!

So, I spent a lot of time in search for a good red wine..  i found one that was good and had the color that matched my purpley theme..  so, i thought to myself at first, i should just buy cases of it.. however, i didn't know how many cases since i didn't know how many rsvps..  and my fiance said there's no point in buying all the wines and where am i going to store it..  so, now that it's closer to the date and i have more of a number of rsvps..  i decided to go buy the wine.. omg?!?  my wine is hard to find!!!  i went to two costcos and within a few days, what was 88 bottles at one costco become 0.. and then the other costco can't locate the 160 bottles that they had.. so, what am i to do!??  i'm just hoping that i can contact the winery and get some cases from them directlty..  cross my fingers they still have that lot..

note to ALL: if you find a wine, especially a red wine, just buy however many cases you think you may need and then store it..  instead of scrambling last minute to figure out what to do when it disappears..
