This is definitely not uniform. I worked on inventory management at Target, and stores had quite a lot of shelf space—to the point where we'd hold large amounts of cheap, non-perishable stuff like cat litter because, well, we had the space for it.

Stores also wanted to look full. We actually had parameters in our inventory management logic to increase inventory just for presentation reasons. If inventory is expensive, having some free, quality inventory can be valuable in and of itself even if it moves slowly.

If you have no shelf space, of course you can refuse the consignment. And this was a really big one, but the shop was initially very happy with it. Advertised widely with it. Brought in more shelves to display it all. From what I understand, it was a very large part of what was for sale in that shop.

But the shelf space is part of it either way... It's not like consignment stores take everything offered. Most of them are incredibly selective.

My wife owns a retail business where some part of their sales is consignment. Taking anything in with only a 10% consignment fee would be laughable, there’s no way that’s a money making deal when you account for all the overhead of a small retail store. My suspicion is the original store owner made a bad consignment deal to sell the Star Wars stuff with only a 10% commission and the new owner didn’t want to live up to it. Of course, at that point they should have just given it all back, but it turns out they’d rather be evil.

> In a low-margin business like retail, "just some shelf space" reads almost like "just some gold bars".

However, in this particular case, the legos were initially displayed as a customer attraction, and then kept in storage. Presumably there's still some inventory cost in storage, but the shelves are clear.

>> The collection will be on display in the store's party room from 10am till 6pm on Saturday, November 11th, and 11am till 6pm on Sunday. The collection will be available for sale immediately, so the best time for pictures will be Saturday morning. The collection will not be stored on-site after hours for security reasons, and after Sunday the sets will be available for purchase but stored elsewhere.
