I have been noticing this Ktown Bricks from a number of LEGO YouTubers being mentioned. Uses official parts with custom pad printing. Their stained-glass windows and potions series are really nice. Very little on their YouTube channel but a few of the shorts show some of the pad printing process.
I get that Amazon wants the cheapest prices possible to bring in customers. Walmart does the same thing with its sellers. What I dont get is why Amazon and Lego are working so hard to squeeze out sellers. If all resellers just stopped buying Lego for resale the hit would be noticeable.
