I got a membership last season and I have still not managed to buy 1 single ticket from the site. For the big matches I do not meet the criteria and for the smaller matches the tickets sell out by the time i get to the front of the queue. Am ending up paying £300 for hospitality tickets or from other sites for matchday tickets and they do not count towards my buying history.
I'm sure hospitalities count towards your buying history as long as you tell them when booking or login to your membership before booking online.
We've all been there mate, my son and I started out exactly the same situation and now up to top cat.
Sometimes you've got to take shitty seats for crap games to get your numbers up. Monday night games against West Brom etc are good for boosting your history.
The "big matches" come later once you've got a few credits.
