McDonalds sells gift certificates in $5 books with $1 certs.
You can also get 3% in your UPromise account by entering the numbers printed on the back of the books. It was 6% if you had an AOL account as well, but that was just cut off. I was buying tham in bulk when AMEX was doing double mile promos. At that time for each $100 it was 200 Miles or MR points and $6 in Upromise. Now it is $3 per $100.
I don't know about other places in Europe, but Starbucks has a card for those $5 cups of cocoa in Zurich!!
