I have the BRAVIA KD55X8509C Smart 3D Ultra HD 4k 55" TV and now wish I hadn't had purchased it!!!!

I have been unable to find 3d glasses ANYWHERE!!!!  I spent £1500+ on a TV looking forwards to trying the 3D out and all I can see is a £50 pair on the Sony site.  I need 4 pairs so need to spend another £200!!!!!  When you look online at, say Samsung 3D glasses, you can buy glasses for £30 (and they're active 3D, too!)

I'm disgusted.  I'll be contacting Sony / Currys about this to get a refund on the TV....
