Yeah, once and a while me and my wife buy a booster box and split the boosters. I prefer buying singles, but it is fun to see her get all excited about it
There's this small shop in finland that sells booster boxes sealed and unsealed (the shop owner unseals them before shipping). Unsealed the booster box went for a bit below 150 euro. Not cheap, but doable. It's something else than a generic date night :)
