ooh ebay is a good idea to look for unircon things fo rthe room too, sometimes people have fabrics and can make bedding on ebay, ive seen tinkerbell fabrics etc, so im sure they have unicorn stuff, if you have the patients to look through pages and pages of stuff on ebay,
Only use paypal though lol, from experience thats the safest way to buy things off ebay , dont ever do the whole money order thing unless they are mailing you the item first.
