Wedding wine recommendation needed

[hotwine]

Welcome to the board, B2B, and congrats! You didn't mention your location, and that can affect availability of specific wines. However, will shoot in the dark and suggest inexpensive, widely-available reds and whites;
Red: Blackstone Merlot (the brown California label, not the grey Napa label). Should be no more than $8 per bottle, sometimes less at Sam's Wholesale club. Have paid as little as $6 per.
White: Kendal-Jackson Sauvignon Blanc. Sam's has it for $6 per. Serve that one chilled a bit, the Merlot at room temperature.

There are many others available, but availability can vary with location.
