Ask The Fray: Where Can I Email Gift Certificates Anonymously?

Help reader OnoSideboard achieve the third level of tzedakah:

    I’m looking for a good online retailer that will let me send a gift certificate anonymously. I’d like something that offers a wide range of choices as I don’t know my intended recipient very well. I’ve checked with Amazon and Barnes & Noble–neither will allow me to email a gift certificate without divulging my identity. Do you know of anything?
