Customer Reviews
Super happy with my Demon Slayer plush!
My order arrived last week and I'm really pleased! I snagged one of those cute Nezuko plushes during their recent sale, and it's even softer than I expected. Shipping internationally took a little while, but it got here safe and sound. Definitely recommend checking them out if you're looking for anime goodies.
Overall positive experience
I decided to try Demonkiller Store for the Demon Slayer Advent Calendar, since I'd heard good things. Ordering was straightforward on their site, no issues there. It shipped out in a couple of days, and I got it in about a week and a half, which was decent considering it was a larger item. The advent calendar itself was well-packaged and the quality of the items inside was better than I expected for the price. I had a quick question about tracking when it seemed stuck for a day, and customer service responded within a few hours with an update. Everything was resolved fine. It was a solid purchase.
Good value with first order
I was looking for some Demon Slayer merch and found Demonkiller Store. They had a first-order discount which was great. I got the Nezuko Kamado Plushie and a Demon Slayer Wall Poster. The discount made it a really good deal, especially with the quality of the items. Shipping was pretty standard, took about a week to get to me.
Fast delivery, good plushie
Ordered a Demon Slayer Plush. It arrived quickly, about 5 days. Plushie was as described. Satisfied with the purchase.

Does Demonkiller Store do anything for free shipping? Like if I spend enough?
Hey, thinking of getting one of those advent calendars. Are they usually legit quality stuff or kinda cheap knock-offs?
