Did you purchase directly from Meraki or through a 3rd party vendor? Typically they can provide the quote history. If you would like to know the cost at MSRP, you can use the Meraki Calculator here: https://meraki.cisco.com/buy/cost-calculator
I would definitely reach out to them then and see if they can provide more accurate 1 and 3 year quotes. They can most likely provide more accurate pricing than the Meraki Calculator page, but The cost calculator is helpful when having those budgetary conversations.
Contact your Cisco Meraki reseller and they will be able to provide you with quotes. You might want to check out this promotion as well: https://meraki.cisco.com/firstyearonus/en (not for license renewals however, but one extra year doesn't hurt if buying new products).
I hope this helped solve your issue. @JohnnyMeraki made a good point to mention the https://meraki.cisco.com/firstyearonus/en which provides additional cost savings. Unfortunately Cisco's EoY is at the end of July so you wont be able to receive any potential EoY savings.
