One year, my giftee listed two DVDs, both $50. She didn't even think about the price, just listed what she wanted and hadn't thought through many options. I had to stalk her mercilessly to figure out other options. (Fortunately, she posted a LOT, so it wasn't too hard.)
Another year, I got a longer list, but most of the items were highly specialized and either not findable or very expensive. I went for the 1-2 mainstream DVDs hoping she really wanted those.
So, I'm a fan of long lists to give options.
