You can use Wicked Bucks to cover any purchase (provided you HAVE enough of them ! LOL) with the exception of shipping costs....For some stupid reason I have ALWAYS had issues getting them to work - until I finally get frustrated and send off an email to support, and then magically the damn things work ! LOL They really ARE a good deal, since they are free - the only bad part is I suppose that if you have to return anyhting, it could end up being just as expensive as if you bought it outright to begin with ! Hehehehe.....okay, maybe that is a slight exageration....okay, a LITTLE one...TINY...possibly even miniscule....hehehehehe....
