I don't know anyplace to buy it other than through our link but I also haven't searched for other places. If you are an Amazon Prime member, you can get it quick like in about 2 days. They used to do trial Prime memberships but not sure if they still do. I am a Prime member. It is very much worth it for us. We recoup the $99 membership fee from all the shipping fees we don't have to pay through the year.
