Double meaning

I think the recent Stella Artois ads are quite eye catching.  Their current tagline is 'Perfection has it's price'.  It's very simple in design and there are no clutter of messages.  But at least one of them made me confused about what they are really trying to say.

'Expensive Until You Try It'

What does that mean?  It tastes cheap??

If I can tweet on BKK-SIN flight Nov.6th, 2009

• I think the plane will be on its wheel all the way to Singapore
• The screen is showing the wrong info, hope the pilot remembers the destination
• Ooh... fish ball green curry...
• Ooh oh... the cabinet in the toilet is held together by masking tape
• At least the service on this flight is much better than SIN-BKK flight
• My hand sanitizer splattered when I opened it -_-

If I can tweet on SIN-BKK flight Nov.4th, 2009

• It's about to take off and I have to use the toilet... URGENTLY!!! >.<

• I wish I can tweet on the plane
• Is it just me, or had TG inflight service dropped dramatically?
• Don't take my coke!!
• I think the guy next to me wants to use the toilet but is blocked by me and my food tray
• Tweeting is like talking to yourself
• Gonna try to sleep now
• Do you put a full-stop "." when you finish typing your tweet?
