Great experience. I ordered 7 Youtooz vinyl figures from Hazbin Hotel and Helluva Boss. I had some requests regarding when items would be shipped, and splitting the in-stock and pre-order items. They were easily able to accommodate these requests, and I already received the 6 in-stock items without issue. Excellent customer service, highly recommend!

I highly recommend to buy games from this respectful company. Their customer service response time just unbeatable even compare to Amazon or other big retail company. Long story in short, I ordered wrong game for order cancellation, I thought most of reply template will be "Sorry to hear that, but order has been processed." But the customer service replied me under 15 min, and informed me the refund.

My purchase arrived in two days. I needed to follow up to confirm something and when I emailed their customer service I actually got a human with a name. We corresponded! It felt like I was talking to the owner and that he had time for me and really cared. These are the good guys and I need to remember to go to Shopville first when purchasing online.
