This was posted when I asked something similarly (I'm just posting everything -- it was epic):

Here's how you're going to get tickets to the opener: 1) You're going to go join the Timbers Ticket Exchange. The week before the match, you'll see hundreds of posts that say something like "I know it's a long shot, but..." requesting to purchase tickets. Go ahead and post one. you might get lucky (I never have with this method.) The morning of the match, you'll wake up bright and early, and refresh said site. Within a couple of hours, you'll have secured all the seats you need from posts along the lines of "Turns out my XXX can't go today because of YYY. One GA for sale, $ZZZ dollars." I've bought as many as 12 tickets for friends in the Army for games against Seattle with this method. A note on the site: All tickets sold have to be listed at face value. Note: In the army, This price can range from 20 per ticket all the way up to 40. Why the range? Well....Season ticket holders get cheaper prices per match than single game ticket owners, and certain single game tickets (Cascadia, opener, closer) are generally more expensive. I only mention the above because while face value is a rule, you shouldn't feel like you're getting slighted if the Timbers website says that GA tickets are 19 bucks, and you're being offered the same ones for 30. The moderators do a pretty good job of clamping down on scalping, and for the most part, I've found the place to be trustworthy. The next step? Twitter. Get stuck in. Start lurking the #RCTID hashtag. Go look up the various board members on the 107ist, and follow them. They routinely retweet available tickets. The benefit here? They're usually retweeting from those they know. I've never had an issue with a purchase made on twitter. How to pay way too much: 1) Stubhub. for the opener? I've seen tickets as high as 100 a pop. 2) Scalpers on the street: Same thing goes. General stadium notes, section terminology, and Facebook/twitter verbiage: Where to sit if a ticket is advertised as "GA", it's the Timbers Army. if it says "The library" it's the covered section down the west side of the stadium. (Called this because back in the USL days, that general region was well, silent. The far Southwest corner? That's the away section. Vs RSL, it'll be pretty tame, as the RSL away fans tend to be a bit more chill than other Western conference counterparts. If a ticket is advertised as the free donut guild? You're looking down the east side of the stadium, under the cover, where the tickets come with food and you guessed it...free donuts. I've had season tickets in the TA since ~2007, but I once sat outside of it, in this section, when my 60+ year old inlaws wanted to attend a match. Alex Morgan was seated directly in front of me. Get seats there if you wanna feel like you're in the 1%. Finally? The south deck. You'll get to have the best view of the opening day TIFO you can get, and throughout the match, you'll get to see the Army doing it's Army thing. If you can't get into it? You'll spend 90 minutes with a soccer match in front of you, back dropped by us lunatics. FWIW, I've been trying to add onto my STH package for 4 years..in this section for this very reason. Gameday before the stadium opens The morning before the match, the front office will hand out wrist bands for pre-entry into the Army. Why? For the first couple of seasons, people would be wrapped around the stadium, sometimes for days on end. The 107ist started handing out wristbands the morning of the game (at various times). This allowed people in line to go home and shower, without losing their spot. It also cut down on the tent city that sometimes stretched the length of the stadium and beyond. If you have army tickets, and you want to be in the lower bowl, Get one of those wrist bands. No, don't worry about the number on your wrist. Getting one will get you into the lower bowl, getting a low number will get you an instagram post, and a long ass wait. Hungry for pregame banter? Go for the cheerful bullpen if you want to stick to the floor, and consider the bitter end if you want brushed aluminium and kale salad. I'll note that the walk in between the two has about a dozen bars, and I reckon everyone has a different suggestion. choosing your seats if it says "GA", it's the Timbers Army. Every section is a little different, and each sorta carries it's own culture. Some of them think they have their own culture, but it's been abandoned since the USL days (EX: the lazy 108's were named such because they used to show up just before kickoff after drinking at the bitter end. They'd arrive to a full 107, and move over a section). Id recommend joining the different groups, and having a look. One scarf, one seat. Once you get into your spot, remember that concessions are 25% off for the first 60 minutes the stadium is open. This is when you guzzle. Afterward, beer goes from expensive to "OMG." Worth noting. Each game, the Timbers partner with a different food truck in town. It gives a bit of variety to the concession food. Check back here for the daily selection: Check here for details. Hungry before hand? Koi Fusion parks a truck to the Northeast of the stadium, in between the bitter end and the stadium. While taste is a matter of well..taste...I contend that Koi is pretty damn solid.
