What are the pull rates for Mega Symphonia?
Pokémon doesn't publish pull rates. Going by what collectors report, a standard Mega era box like this one typically holds three Art Rares, a Trainer SR and one card of SR or better as the main hit, along with about four Double Rare Pokémon ex. Special Art Rares turn up in roughly 1 box in 3 to 6 and the gold Mega Ultra Rare in about 1 box in 50 to 55. These are unofficial figures from collectors recording their own openings, so no box is promised any of them. Our pull rates guide explains where they come from.

Buying Mega Symphonia in Australia
We are an independent seller based in Sydney, so ordering a booster box here means it ships domestically instead of turning up weeks later from overseas with a customs bill attached to it. Everything leaves Sydney tracked and insured within 1 to 3 business days (we dispatch Saturday to Wednesday), then Australia Post takes 2 to 5 business days to most addresses. Prices are in Australian dollars and already include GST, so the number on this page is the number you pay.
This booster box is in stock right now and is dispatched within 1 to 3 business days. If you want the detail first, there is the full shipping and tracking page and the returns policy.
