I'm assuming the best time to get on the shop and get deals is right at the start of the new week for the game.
But what about the rest of the week? is there a specific pattern or time that new designs go up or is it all randomized and just luck of the draw that your on and looking at the shop when the design is posted?
Usually gucci911 Diva1 trishytrash give you a 10 minute warning or something before they post.
