Most people on here would probably choose Ebay, over Amazon given the high number of posts relating to people finding better deals or an actual photo of what they are buying. On Ebay
I've bought things like 2 PlayStation 3's I bought from amazon, though one still works I'll give the seller that, but one had the case peeling off and the other one was covered in brown sticky stuff. The one covered in brown sticky glue like substance broke after I had it cleaned and it's laser replaced. the one with the case peeling off, might still work, but I need to fix it from something I did to it.
However I bought a used copy of "Ben 10 Alien Force" (game) for PlayStation 2 for under $10 USD and that included the shipping. off an amazon seller. also in great perfect condition with manual and case recently.
But, I also have bought games that were PAL version. A different Amazon seller. didn't say, they were the PAL version though. I never bought a single thing off Ebay because something does not feel right about Ebay. I'll only use Ebay if I have no other choice
(edit) I answered the question but the OP"s post has nothing to do with the actual topic.
and recently I overheard a public conversation about Amazon and it's didn't sound good
