[RBS] Seeking cheap 10cm preferably Ashkenazi Mezuzah

Have just been asked to purchase and send with my mom, who flies out of Israel immediately after Shabbat: A 10cm mezuzah, preferably Ashkenazi, preferably as cheap as possible (does not have to be mehadrin). If you can help, please email me. Please don't reply to this email close to or after Shabbat (Parashat Mikketz) , as it will be too late. TIA, Melissa
