Does anyone know of some cheap non food collections? A lot of the achievements look like they are collection related but I've priced some of them and they are quite expensive. I'm hoping to spend no more than 1.5 mil per collection for now. I have been putting plushies and beanbags in my collection as I go but I'd rather focus on just getting collections for now.

Honestly, all the collections can get pretty expensive once you start getting to the really pricey items. However, there are plenty of items that are very cheap to begin with.

You could always try for the numbers based Achievements (like Gourmand or Filled Wardrobe) instead of the item based achievements that require you to have x, y, and z. Because those items can get achievements, they are going to be more expensive.

I started with beanbags -- you can get a fair number of those ones for reasonable prices, but as pointed out there are really expensive items in all collections because of things like the Cash Shop and Blackheart Hollow. Go for quantity over specific items if you just want to go for the achievements.

What do you mean by collections? Like, a full collection, or just like sets of items for a different achievement (because like there's way over 3k plushies, and it's going to run you way more than 1.5m??). You can probably do some of the smaller achievements (e.g. "Collect all the alphabet stickers" etc.) for 1.5m each though, it's just a matter of figuring out which ones and maybe trying some restocking/vending/Mystery Box depending on what you're looking for

the collections that are in Achievements are pricey because they are Achievement-related. Therefore they are unlikely to be cheap, but pricing them out is what any of us would have to do just like you.

Some of the subcollection Achievements are restockable or based on Game Prizes so you can get them by restocking or doing stuff. This will save you some sP.

Like people have said, everything gets expensive eventually. But if you do a lot of quests and just generally participate on the site, you'll end up being given lots of food/books/plushies/beanbags/etc., and you can add them to your collections as you go along. Usually for quests you'll break even or make money anyway, and once you use the items you've got in your collections, you're saving sP! :)
