J & R is great. They business model to survive is based on usually having lower prices than stores like CC and Best Buy. Sometimes its only a couple of dollars, but its nice to see the effort. And they often have harder to get items.
This is the only store I know of that has say, 8 X 14 photo paper for a reasonable price.
However J & R is best for people who live in NYC b/c their shipping prices aren't the best.
But yes, they are totally legit/
