So a lot of the stickers that I now need for my collection are old cash shop stickers that come from the various variety packs such as Etc. Do the sticker variety packs ever restock back in the cash shop? If not do any of the stickers from these packs come from any of the cash shop chance machines?

Yeah, they've been back in the CS now and then. The Black Friday sale in November is usually when those kinds of things come back, but I think there have been other stickers that came back outside of the sale and/or stayed in the CS after it ended

Thanks! I completely forgot about the black friday sale. I really really hope they make a comeback for that. I am lazy but I need to see which stickers are actually even worth waiting for that or just buying them in user shops. I have been meaning to do that but I keep putting it off and everytime Major Drills asks me to get the Hustler to add a sticker I just wind up buying whatever is the cheapest on my wishlist but they are becoming really costly now.
