Where in the account manager does one go to see the tiered pricing for their seats?
In the account manager you can see the individual prices in each ticket or you can see the price by game in the invoice summary. As GG noted, you can get a bit more info from printing an invoice on nyrmembership.com but neither of these options shows the date of the games. You should also have gotten an email from your rep which has a link to a page on nyrmembership.com which will give you the full schedule by tier. I haven't found out how to get to that page directly, though. I like it better because it has the dates which makes it handy to email to family/friends etc.
BTW I looked at the terms on the tickets loaded (bolding mine).
"Your ticket is a revocable license to attend the event listed on the front of the ticket and is subject to the full terms found at
www.ticketmaster.com. Such license may be revoked without refund for noncompliance with terms. Unlawful sale or attempted sale prohibited. Tickets obtained from unauthorized sources may be invalid, lost, stolen, or counterfeit and if so are void.
Your ticket may not be resold for an amount in excess of the face value of the ticket without the written consent of issuer. Maximum resale restrictions may apply, e.g.: PA: greater of $5 or 25% of ticket price plus tax; NY: if venue seats more than 5,000 persons, ticket may not be resold within 1,500 feet from the physical structure of this place of entertainment under penalty of law. In the event a legal baseball game is not played, ticket may be exchanged for same price seat for either: (a) rescheduled game, if any; or, if applicable, (b) any baseball home game within 12 months of original game, if available. Complimentary tickets not exchangeable or redeemable for any benefit offered to tickets with a dollar value. TIME, OPPONENT, ROSTERS AND DATE SUBJECT TO CHANGE. Your ticket may not be used for advertising, promotion or other trade purposes without the written consent of issuer. Applicable taxes are included. Holder assumes all risks occurring before, during or after event, including injury by any cause, and releases management, facility, league, participants, clubs, Ticketmaster, and their respective affiliates and representatives from any related claims."
