Today (Wednesday, 3/5) Amazon has Sony memory on sale. Personally, I've used Sony SD cards for years without any trouble, and they are a good deal compared to comparable SanDisk -- and even better on sale today. SD, micro SD, and thumb drives are on sale. I've already picked up a 32GB, 94MB/s class 10 SDHC for $29.99, 2-day shipping included.
I have a few of the Sony 32GB 40MB/s cards, and those are going for $16.99 today, shipping included. 50 cents a gigabyte - pretty good. The only drawback on these is that when shooting my a77 at 12fps it takes longer to clear the buffer than with the faster card.
Just thought I'd pass along a good deal.
