General question about 2 sellers of TY G03

Hey, I was trying to find some TY G03’s and give them another shot. I was wondering why tere is a $25.00 plus price difference on the same media but from 2 reputable stores. here are the links if anyone wants to check it out Blankmedia.ca and NCIX.com

I bought a 50pk from NCIX and at 16x in my LG-4163B A105 the scans did not come out so nice at 16x, ill try to attatch the scans or link them. They came out way better at 4x but thats not right its 16x media.

The picture thats uploaded here was burned at 4x but on 16x TY G03’s
