You will not be able to get the 6 game flex pack early on in the season, 10, 15, 20 packs will be your options, with that being said if you get any of those packs you will be able to get home opener and Canada Day. If you're just looking to sell those tickets pick weekend games with giveaway days (Always Sundays) and Yankee and Red Sox match ups, as for location, the 200 level infield or baseline are the best in my opinion.
