I liked the presale as well.
I also bought tickets for the second night in San Fran via Ticketmaster. The ticketmaster tickets have already arrived but not the presale tickets.
I am not worried as Artist Arena (presale) tickets that I have purchased in the past always arrived way before our trek across the country.
My only comment is that the envelopes are not well marked (for obvious reasons) and I nearly tossed them as junk mail the first time.
