Websites tht sell pokemon cards. Oh boy. Let's start with single packs. The more expensive cards way more than regular cards so often sellers will weigh packs. Whether they keep the good ones or not I wouldn't know, but they do, so be careful. Sometimes people sell world championships cards as originals. Be careful of those. They are worth nothing. They are not playable nor are they collectors items. Half of the fun of trading cards is opening the pack and not knowing what you get, but there are websites that sell single cards. You may ask why and I have the answer for you. Collectors. Some people whent the whole set, but are too lazy to pull till you get the whole set. I was looking at one of these sites, just out of curiosity and I had this idea. What if I had a friend buy a lot of random pokemon cards. They don't have to be good, just buy them and put them in a box. If you get a single sleeved pack from Walmart it is 1.00 without tax. Most websites sell each basic card for 0.99 cents. In a sleeved pack you get around 7 cards per pack. So a basic pack would be worth 6.93 dollars. In order to get your money's worth on cards without wasting any money on them you could get singles to complete the set, or you can sell duplicates.  But then there are other cards that are also pretty rare. For instance, missprints or error cards.  They can go from 10 dollar to 5,000 dollars, depending  on the card, type of missprint and condition. For instance take a trainer computer error card, in mint condition that  error was a miss cut. This card whent for 174 dollars. But why?
