I live in Finland.
Ordering from LuckyStarDVD took about 1 month for the DVDs to arrive. It's ok.
I've ordered from 1price three times now and every single time the DVDs have arrived super fast: in only 1 week (add one or two days to it).
There was a mistake from 1price though as they sent a wrong DVD to me once. I had ordered perhaps about 15 DVDs and for some reason they messed up one time but when I ordered from them the next time they sent me also the DVD I didn't get earlier.
The latest purchase happened on January.
Notice that for international orders they send only the actual disc and the cover paper. Not the cases. That's to keep the shipping cost lower. So you need to buy the empty DVD cases yourself. Those are cheap though and it's really worth time and money to do that. When I order, I usually try to find 5-15 DVDs I want. I pick some a bit more expensive titles and some cheap ones. Most sellers give you extra DVDs when you order many. In the end, buying many movies and putting 2 or 3 euros/pounds to buying a pack of empty DVD cases, you'll likely end up getting the movies cheaper than from anywhere else.
I wholeheartedly recommend that site for you.
