What I found interesting: For example, the 50th Anniversary books were only offered one at a time. All three were never offered at the same time. Almost like they would sell one out, then list another book.
Clothing sizes- yes, I agree strangely limited, but recently noticed the sizes would change from the initial restock size
(example: when 1st restocked offered in small, when I recheck link 30 min later, offered in medium and large )
