I don't consider myself extremely religious like those customers. I've never had to play $6.66 for anything, but if I did, I'd probably simply add or remove an item - I wouldn't scream, “I don’t want it! The devil’s already marching through the stores.” or “Your cashier is touched by Lucifer himself! She needs to be baptized in the holy waters.” or anything like that.

In fact, as I was making the first frame of this userpic, I noticed that the area I was about to select to crop was almost 666 pixels wide or tall, so since it fit, I went ahead and selected 666x666 areas for all of the frames (then scaled them down to 100x100) and even put the numbers 663-666 instead of 1-4 in the filenames, so if I ever have to pay $6.66, I might not even end up adding or removing anything. Or I might. It all depends on how many of these ominous signs I've been seeing recently :P
