Go to a Real D theater and take home as many as you want.

Yeah, what he said. I've got a set of RealD glasses sitting right here on my desk. The ones that came with the monitor are more comfortable, but these work just as well, for the times when I'm not the only one watching 3D content.
I have to step in here (just became a member! ) to recommend the LG AG-F216 & AG-F214, both of which I got thru ebay a while back and am still impressed by their build quality. The former contains 6 pairs of assorted Cinema 3D glasses, and the latter 4. I decided to get these sets because they include 2 clip-on type glasses each (for us prescription specs wearers ) but I must say the assortment is very comprehensive: 2 pairs in the AG-F216 are of a more lightweight-designer-fashion-cool type. 1 of these is a metal rim frame (my "Neo" glasses!) which leaves the plastic film exposed and you'll see it's not that fragile. It's reasonably sturdy IMHO. What's more, the other 2 are for children; made to withstand normal kids' abuse without sacrificing "cute" looks. My 4-yr-old and a few nephews/nieces haven't even scratched them a bit. The AG-F214 will only give you, apart from the clip-on type, 2 pairs just like the white/orange ones you got with your TV.
So, I now have 6 from the AG-F216 set, 4 from the AG-F214, 4 which I too got with the TV (white/orange), AND 2 from a RealD theater. Of all those 16 pairs, the ones we most avoid are the RealD, since we consider them to be heavier and, generally, less cool-looking. BTW, the film in these are as thin as the LG ones, in case you were wondering. Just my 2 cents worth .
I don't know anyone that returns the theater glasses. Its not like they ask for them back at our theater. I have plenty of kid size ones if people need them. I see that there are a lot of people now selling Polarized sunglasses that you can now use in the Theater and at home. They are trying to get the dual purpose out of them.
