TL;DR: The Pokémon TCG 30th Celebration Booster Bundle is on sale for $89.86 at Amazon.
Tracking the Pokémon TCG market is still a wild ride. Sometimes we're looking at record-low prices on new releases. Sometimes we're looking at a "deal" that's actually above market price. It's all about availability and demand.
Demand for Pokémon TCG 30th Celebration Booster Bundles is obviously still high. The Pokémon TCG 30th Celebration Booster Bundle is listed for $89.86 at Amazon. That's above the $74 market price on TCGplayer, but actual listings for below $100 on that marketplace platform are scarce.
Amazon seems to have plenty of stock at a reasonable price. In this case, that constitutes a "good deal."
The six-pack Booster Bundle is a popular pick for collectors. Each booster contains six holographic cards, including one of 30 different Pikachu rare variants. The collection features Mewtwo ex, Mew ex, Umbreon ex, Salamence ex, and Greninja ex. You're unlikely to pull the most valuable cards, but you never know. That's the joy of ripping packs.
