So, I have two different questions about the shopping site, Amazon.com. The first one is about gift cards. Let's pretend I got a gift card for $400 from amazon, and I wanted to spend only part of it, say $100, would there be $300 left on it, or do you have to spend the entire thing at once? Second, about a pre-order shipping with other in-stock items. Today, I ordered 4 items. Two of them are already released. One other item is going to be released mid-september, and the last, fourth item will be released mid november. Since I chose free super-saver shipping since I spent over $25, it said that my order will ship in as few shipments as possible. Does that mean I will have to wait til november to get the entire order, especially since i chose that shipping option? Thanks in advance!
