Where to Buy
Apple Mortar's rarity depends on where you live. For people living near Mexico, these are fairly common, but for people in other places around the world, these are very rare. If you don't live near Mexico then your best bet to find these is if they show up on eBay. Or you could use a Proxy Buyer, which is a hard and long process.
