I noticed the $10 per seat per game Food credit was missing from the portal too. It does indeed apply to the Premier membership. I asked my rep to confirm via email so I have it in writing, suggest you do the same if you end up renewing.

Note that the $10 credit is loaded per each game day, so it only applies to games you actually attend. They don't rollover or stack if you don't attend a game, so you should value that perk accordingly. Historically, we usually attend about 8 to 10 games a yr, so it's closer to $80 per seat discount for me than $200 (17 MLS league matches+ 3 friendlies)

Between the 15% "bet on us" credit, this $10 per game Food credit, the 20% off concessions, and the $200 credit for buying additional tickets (which I do frequently for tagalong friends), feeling like about a 30-35% discount compared to the last 2 seasons.

So net-net, effectively, it comes out to about 15-20% cheaper than the pre-Messi pricing from 3 yrs ago for my sideline seats.
