They have different prices if you are going to Craftsy via an email or outside link promotion. I had an email for a sale and went there through the email and the sale prices were there... I went back there directly without clicking through the email and the prices were different. That might be the difference. I don't really think it's the app's fault. I think it just depends on if you are going to Craftsy for a sale through a direct link to the sale if that makes any sense.
