Memory cards for any product aren't really hard to come by, but grabbing a decent sized card at an equally decent price point is where the challenge lies. Throw in the additional factor of finding a decently priced card that has enough storage for you and happens to be a good quality brand makes it even more difficult sometimes. The good news is that you can find a handful of Sony memory cards in both regular SD format and microSD format at up to 60 percent off right now from Amazon, in varying sizes as well so there should be a size for everyone.
If memory cards aren't necessarily on your wishlist, there are a couple of Sony branded flash drives on sale as well, in both 32GB and 64GB sizes. As for the microSD cards, you can find them in sizes of 32GB and 64GB as well, and for the regular SD cards there are sizes of 32GB, 64GB, 128GB , and 256GB on sale for up to 60 percent off as well. All of the memory cards have listed transfer speeds of up to 70MB/s, and all of the memory cards are listed as waterproof so they'll be fine should they end up getting a little wet.
