[quote name='Duo_Maxwell']NeoRanga's a pretty good series overall and as moiety mentioned that's a pretty unbeatable price for all 6 DVDs. I have the 1st 3 volumes already, but if I didn't I'd be on that deal (actually it may even be cheaper to just get the deal really).[/quote]
That happened to me with Excel Saga. I needed disks 4-6, but then the Imperfect Collection came out, and Best Buy had a sale, and i had a coupon, so it was cheaper to rebuy the set, especially when I could then trade/sell my original disks 1-3.
On TRSI, they should tell you the inventory status of the item on the item details page. But most of the things on the specials list, especially any really good buys, you might have to wait a bit for. I don't mind, I get economy shipping [usually free] and since I'm saving so much money, I can deal with waiting.
I had to wait about 2 weeks for one disk, and about 3 weeks for one box set one time.
