Great! I've been putting purchasing Vol 5 and missed the DeepDiscount deal last week. I had hoped Amazon would have a similar deal soon but this is much better.
A small warning, I had to hit two differenct Costco stores before I found the LT sets. You may want to call ahead as it appears not all of them have them in stock (yet?).
I called one of the local ones here in LA and they said they have 65 of them, I asked him to check the floor and he said they were still in storage. He thinks they will be out in the aisles tomorrow.
After my third trip to Costco in as many days, they finally put these on the shelf today and I was able to pick up Volume 5 and complete my collection. For those without Costco membership, the first four volumes are on sale for $26.49 at Amazon.
