i caught the Princess Nine deal a few days ago.
I hope it isnt the same as their clearance sales, while 20 after shipping is an ok price, I dont know if it's worth it if i have a hole drilled through my UPC.
Lately the deals have sucked, monster rancher, a few Andromeda discs (total waste, I don't even understand the Andromeda volume labelling scheme, they cant seem to pick one and thats going to negatively affect sales in general) and today's deal is extra worthless: Ignoring the fact that you can get the complete series brick from DDD for 29.99 (non-sale) and these are 7.49 each, it's only half the series, 4-6, for 22.47. Add shipping (5 for the first item, 1 each additional), and thats 29.47.
But check out rightstuf.com, and you can get the individual volumes on clearance (if thats your thing) for 4.99 each, with free shipping over 49$. That's 29.94 flat, for the whole series, and you dont even have holes/slashed on your cases.
I dont really see the point of getting individual volumes if you dont have a box and can get the brick for the same price, though.
I say bookmark this link and check it every day if you like the stuff ADV puts out. occasionally you can snag a good sale. I'll jump when they get the rah xephon set up on there.
