Shout out to Central Market here in Houston. They routinely have ~20 or so varieties of apples in stock and will happily (more or less depending on who you ask) cut one up for you as a free sample in the store. I discovered the opal gold this way a few years ago, though I've been a bit disappointed recently as it transitioned from seasonably available to year round.
Envy vs Fuji comment - recently our Fuji's have been a lot larger (excess of 1 lb), whereas our NZ Envys and Smittens (my new jam) are about half the size. My sense is that larger apples often don't have as great if texture, and if you're buying by the pound but eating by the apple, the smaller fruits are better value even if they're slightly pricier.
