Went to the game tonight and purchased a single ticket in the 500 level for $15 USD off StubHub around 7 PM, when most of the tickets in the 500s were listed at $30-$40 during the day. From what I saw, ticket prices were dropping drastically as you got closer to first pitch. The average price for a 500 level seat around 6:30 was still in high 20's, low 30's. Around 7 PM, I was seeing so many listings below $20, and I'm sure many tickets in the 100 level were dropping as well.
If you can be patient and wait it out until the last minute, then you can scoop up seats close to face value or cheaper for the remaining regular season games. My close friend lives near the Rogers Centre, so I was able to get my tickets printed easily right after I bought them. There is the possibility that you could end up with nothing, yes. For the postseason, tickets will be higher than face value obviously, though for the prices people are listing 500's right now or any other seats, the prices will drop I'm sure closer to first pitch if those same people haven't moved their seats yet.
