Can I trust these eBay users/companies?

OK, I'm about to order in a bunch of anime from Malaysia, the thing is I'm a little curious if they would put this kinda price on these anime complete sets, $15-30 Australia. :/

It just doesn't seem right I ordered in Elfen lied (1-13) last week and it cost me $85, and each of these are $15 to $30

So if anyone could have a look at them for me, it would be greatly appreciated, i already had a look at their feedback, and it's excellent! But somehow I'm not completely sure of it.

I'm a newb when it comes to ebay. lol ^^
