Hi ladies,
I got married in Oct 2008, and haven't been on this board since then, but I saw a pair of really cute white wedge flip flops at Sears that would be great for reception flip flops. They were only $16. The heel was approx 3 inches, so if you're looking for high wedge white flip flops, check them out.
I remember having a hard time finding them, and when I finally ordered them online they were around $35.
Good Luck with all the planning, I loved every minute of it!
