This purchase is for the initial blueprint and the correct number of cogs to deploy your first Bot from the blueprint. You will receive an error if you already own the blueprint, and not be allowed to buy another. One per account.
Before you try to purchase any of them you may want to check the Munzee website Redeem page to see if you already own the blueprint. If you see it on that page you aren't able to purchase it again. Many players received some of these blueprints in December as part of the Holiday Mailbox. You are NOT able to purchase the blueprint again.
All of the details for each Bot is also listed on the Redeem page which includes information about Cog cost, Points, Scatters, and length of time deployed.
All blueprints may not be available year round and may become "seasonal" or "limited edition".
If you are looking for the RUMbots, they are only sold via the authorized resellers. For a list of reseller stores please visit munzee.com/retail
