The phone number for Tanurei Yerushlayim (Jerusalem Ovens) in Israel is: (011) 972 545 512-800. I don’t think they speak English, so if necessary have a translator call for you.
It is probably too late to get one in time for this year, but since this post was started last year and is still going, it is likely that it will still be seen next year, or someone may take down the number now, to buy one next year.
