I purchased Spamalot tix for about $112 each from Telecharge.com. Now as I'm browsing around, several sites (like Ticketsbox and TicketsNow) say "Spamalot is sold out...but we have tix." The tix on these sites run about $175 for the same seats as mine. My Question: Is telecharge really the "official" agent for the Schubert (as claimed on their site)? Or is there something wrong with the tix I bought? Why the huge price discrepancy if you can just go to telecharge (the "official site") and get the same tix for less, for a "sold out show"? Thanks for your help

Telecharge is the official ticket seller for Spamalot on Broadway.

One thought is that Spamalot is not sold out on the dates you bought tickets for. Clearly it isn't, or you couldn't have bought them through Telecharge. But it is sold out for many dates. So, places like TicketsNow can truly claim that it's a sold out show (it is, sometimes), and try to convince you that you'd better buy from them because you won't find tickets elsewhere.

If someone does buy through them for lots of money on dates that are not actually sold out, I guess it's a case of buyer beware. They should have checked first. Unfortunately, not everyone knows this, so the reseller sites are taking advantage of some buyers' naivete.

First of all, you did not mess; your tickets are legitimate.
As for the $175 seats, it's most likely a situation where those other sites bought the tickets at regular price and they make their money by selling them for a higher price.
I don't understand what you mean when you that those sites have the same seats as you have. For the same performance? That's impossible!

HowardR, Sorry, I didn't mean exactly the same seats. Just seats in the same section, a row or 2 back.

Okay, now it makes sense.
You can relax now! Your tickets are safe. You ordered them from a reliable source and you paid the right price. (And consider yourself luckier than the people who paid $175 and are sitting next you!)
