Since I can't get them here in Australia at that price, I went onto Threadart and ordered a further 6 blades at 2.99 each. They are NOT Olfa but will fit the cutters. I payed about $28Au for the 6. About $4.50 each all up. Still better than $12 each any day. That is with p&h plus exchange rate too. Thank you for reminding me to check Threadart out again for the blades. I will give my daughter 2 when they arrive next week. She is a beginner quilter so all the help she can get the better.
