Ok, I've done 4 of these shops, and each time I've received a score of 9. The explanation states that they had to do some "minor editing" on the receipt page.
I've looked over their sample page and I'm filling in the form exactly as specified. Is anyone else running into this? I don't mind getting a 9, I'm just curious as to what I'm doing wrong. And of course they don't respond when you inquire.
