I'm just glad that out of all the Pokemon TCG products out there, the scalpers aren't touching the only Pokemon TCG product I collect.
Booster packs and box sets have risen in price at my local game store, but Theme Deck prices remained the same, unless you are talking about that Vivid Voltage Charizard one.
When I am too cheap to spend any money, I always prioritize Theme Decks, now V battle decks, when it comes to Pokemon TCG purchases. This is followed by the league battle decks. If the product has a preconstructed deck in it, I have to buy it. I sometimes buy loose booster packs here and there, and at one point I bought Elite Trainer Boxes from every set, but I stopped. Some people value the single card, or maybe they value the sealed products. For me, I don't value the sealed theme deck. I value the 60 card deck as a whole, and if a card is missing or a card is replaced with a different one, the deck is incomplete. I just have to open the theme decks I buy to make sure that all the cards are there, and none of them are replaced by another card or missing. I got mad when I bought a EX Power Keepers theme deck, the one with Mightyena in it, and it was missing a fire energy. Another situation was when I bought the Rampardos theme deck from Diamond & Pearl Mysterious Treasures, and it was missing one of the trainers. I forgot what it was though.
Although I value theme decks a lot, a 2nd or more of the same theme deck is worthless to me. At least if a kid wants to play the Pokemon TCG, the Theme Decks and V battle decks are still available. You don't need the best cards to be able to play the game.
