If you can't make an animated gif yourself, there are some out there that can be used. I'm not sure where, but they do exist. Try doing some web searches for free shipping graphics, etc.
There may be a way to make text blink with HTML, but if there is, be warned that those codes don't always work with all browsers.
What about just making the text bold and a bright color while you're working on the blinking idea?
