Yeah. I ordered a particular 6 book series and the first 5 books were expensive. So I got those out right away then debated back and forth about what other 4 books to get with that last book from the series. I guess its possible any of those first 5 could have gone OOS while I was deciding on the other 4 books.
The reason I wish I had done all 10 on one order is because I'm like 95% certain that series is going to ship from the same store. For all 6 of these books to be in stock at the same time makes me think someone just traded in their collection to Hastings. And I think these books are a decent size so Hastings is going to have to spring for a box, I pray. If all 6 books are coming from the same store I'd hope the employee would notice my two orders and put all 6 in the same box, rather than do 5 in a box and 1 in a bubble mailer or whatever. (I have a sinking bad feeling they're going to jam at least 5 of the books in one of those giant bubble mailers and the bubble mailer and the books are going to arrived damaged.) But I don't know if their computer allows for combining shipments like that. I somehow doubt it, given how shitty their system is.
Swamp Thing isn't abnormally sized; I have three of the hardcovers you ordered, and they're the average GN size and thickness. Good luck with whatever they ship them in, Book Three is pretty valuable.
