Seeking Mitzvah recommendation

[oredon]

Hi ... I'm looking for some suggestions for both red and white wines I can purchase(under $10 per bottle)for a June 2000 Bat Mitzvah party! Would like to purchase by the case for savings and will have to incur a corkage fee of $7.00 per bottle Food will be buffet with variety / Salmon as main course. The event is both indoor and outdoor and it could be quite warm outdoors.I realized that the wines the caterer offered were all over 16$, with many in the 20-25$ range. I'm wondering if any of them were worthy of that price and wouldn't I do better to bring in my own? Can someone also advise me on how to proportion the red /white. Will most folks choose one over the other. I've heard white is generally more poular yet all my close friends prefer reds as I do! I have easy access to Trader Joe's, Beverages and More, Costco, & Cost Plus. I've heard these are all great places to find wine steals! Thanks!!
