I bought my copy of Gunbuster from the MusicMagpie eBay store and it turned up in pretty good condition, booklet and all (it was the US set), I also preordered the Durarara!!x2 BD directly from their site and while it took them like a week after release to bother sending it, it also arrived fine. Anecdotal evidence of course as it does sound like your mileage will very much vary.
Psycho Pass Season 2 - Got it from Zavvi while it at a reasonable price £33.99 I know its been a bit cheaper but its still an acceptable price. Hoping to pick up Owarimonogatari pt 2 later this month but will depend on my cash flow.
