no it's too late when buying cards online you must be careful because ppl suck. if a site says something like "not in original box" or "used" or "not original packaging. it come be tampered with, if u buy cards and notice the packs look "odd" or like it was reglued, don't open them and get your money back, when sites are trying to scam you usually they have a "no return policy" so dont even buy from them.
make sure it's from a site that still has "factory packaging" that way you know it hasn't been opened, try not to buy from card shops with packs that aren't individually wrapped, what they do is get booster boxes weigh them, open the heaviest boxes weigh the packs open the heaviest packs to get the good cards and sell the rest........
fake cards usually have incorrect information like mispelled name, different wording, no card number(bottom left corner, or the silver or gold square is even with the border(in real cards the square falls slightly over the gray border. and in fake cards holo cards are typically wierd colored. and in most fake card the entire star for the level is visible(in real cards you can only see the top half of the card)
and the miscoloring the above ppl are talking about isnt usually because of "lack of printer ink" in older sets its common for 1st edition cards and unlimited cards to be colored differently, if u get a 1st ed card and the same non 1st ed card the non 1st ed will have a lighter tint to it.....
upload some pictures so i can tell if they are fake or not
