Unfortunately, any new item will not have a discount. They do give you points for each item that you purchase that you can use to discount future prices. However, there are a couple things to note. First, you don't actually earn the points until about 30 days after the purchase. Second, if you use points to purchase an item, you do not earn points on that item. In that respect, it is better to use points on a cheaper item or to save up enough points to purchase an item for free or near free. I believe you get one point per one dollar in item price and each point is worth a penny.
In terms of Hot Toys, if they are anything like the Marvel line, they usually sell out and hold their price on the secondary market so finding a bargain is quite tough.
