They have stock of both 120 and 220 of this film according to their website. This is in Canada, so it will have to cross the border to get to you.
But instead of ordering from the internet, its really best to call them with their 1 800 number and find out exactly what quantities they have left. I did this when they still had some Verichrome Pan and I bought all their remaining stock of it down to the last roll. Keep in mind their phone can often be busy, so you have to keep trying during the day to get a hold of them. They are especially harder to get through near the end of the business day, so calling early in the day is best.
