[/quote] Indeed. I think that's mostly by design. They want to light a fire under your butt to ensure you spend the money to take advantage of the promotion as soon as possible, rather than just sitting on it until the last minute and possibly not doing it at all. It's just a marketing strategy.
Even so, I wouldn't wait extremely long, mostly because the longer you wait, the longer it'll take to receive them. I do think you can afford to relax just a bit, though.
