As suggested previously in the San Andreas Mercenaries DLC, this title's Halloween event has now started, allowing Special Cargo business owners to earn double bonuses for seven days by accomplishing Special Cargo Sell Missions. This makes it very important to know exactly how to start doing these jobs. First, you will need a place from where you can source or buy the supplies for the missions. Purchasing an office is one of the best options for this purpose. GTA Online players can buy an Executive Office from the Dynasty 8 Executive in-game website to get started with the Special Cargo business.Here are all the available Executive Office locations in the game currently:Lombank West (Del Perro) - $3,100,000Maze Bank West (Del Perro) - $1,000,000 or Free with Criminal Enterprises PackArcadius Business Center (Pillbox Hill) - $2,250,000Maze Bank Tower (Pillbox Hill) - $4,000,000Purchasing an office will give access to the CEO's computer, which can be used to start sourcing cargo. However, one will need a Warehouse first to store the cargo and establish the Special Cargo business. That is also a purchasable property that is only available to buy once players register themselves as CEOs in this title.There are three different types of Warehouses:Small - 16 cratesMedium - 42 cratesLarge - 111 cratesHere are all the available Warehouse locations in GTA Online, according to their sizes:Small WarehousesConvenience Store Lockup (Rancho) - $250,000Celltowa Unit (La Mesa) - $318,000White Widow Garage (La Puerta) - $360,000Pacific Bait Storage (Elysian Island) - $376,000Pier 400 Utility Building (Elysian Island) - $392,000Foreclosed Garage (West Vinewood) - $400,000Medium WarehousesGEE Warehouse (El Burro Heights) - $880,000Derriere Lingerie Backlot (Del Perro) - $902,000Fridgit Annexe (La Puerta) - $925,000Discount Retail Unit (Downtown Vinewood) - $948,000Disused Factory Outlet (Strawberry) - $971,000LS Marine Building 3 (Elysian Island) - $994,000Old Power Station (Rancho) - $1,000,000Railyard Warehouse (La Mesa) - $1,017,000Large WarehousesWholesale Furniture (Cypress Flats) - $1,900,000West Vinewood Backlot (West Vinewood) - $2,135,000Xero Gas Factory (LSIA) - $2,365,000Logistics Depot (La Mesa) - $2,600,000Bilgeco Warehouse (LSIA) - $2,825,000Walker & Sons Warehouse (Banning) - $3,040,000Cypress Warehouses (Cypress Flats) - $3,265,000Darnell Bros Warehouse (La Mesa) - $3,500,000After getting a Warehouse, you need to log in to the computer that you got after purchasing an Office as the CEO again.
