You get a free Lapras during the game, though. If people want Lapras, they would probably already have that one.
I do suggest Wondertrading some of them. I've got like 2 boxes full of foreign Pokemon right now. I have better luck catching people outside the US either late at night or early in the morning. Also get more IDs for the Lotto too.
Last night I found a shiny Barbaracle in a Friend Safari. I was hoping to find shiny Pupitar or Boldore instead. Nope, stupid goddamn Barbaracle. I gave it to my roommate. If he hadn't wanted it, I was going to Wondertrade it. I almost considered KO'ing it out of spite. >:(
Yeah I know, stupid ungrateful me, but I really dislike Barbaracle.
