Has anyone had experiance with money/leveling from http://www.luckygolds.com/ .
Because i never heard of them and they are spamming in SW.

Personally, I don't trust any website that advertises in game, because I feel like Blizzard probably keeps close tabs on them. That being said, shop around multiple gold sites, and look at prices, stuff that seems too low to be real is probably gonna be a scam or a potential ban. Overall just use common sense when looking at sites, surf around, google the name and see if any reputable reviews come up.
