I heard that the charmander line was incredibly rare.
I have found a website that sell the charmander and charmeleon at £4.96 and the charizard at £9.99.
i havn's posted tthe website as i think that would be advertising (really ?).
It wouldn't be advertising as long as it's not you selling them (or telling others to buy them).
That's not a bad price, but they're not THAT rare (one a box, not a big demand to top it off). I would check into the reputation of the site that is selling them if it I was considering buying them.
I don't believe it's one a box, because at my pre-release it was 2 per box. I would only want to run that card if they somehow decide to make a LV.x Charizard.
