It worked this time and I think I know what I did wrong. I copied the SHARETHELOVE code wrong, I actually copied SHARE THE LOVE from further down the page. This time when I tried it popped up that the coupon code was invalid. It didn't do that before, so I suspect I copied the wrong text but didn't get the message. Thanks for the link!
