Lens Filter Price spreadsheet (shared)

I did a quick research this week and I figure I'd share them here.
Basically comparing 4 stores, between various brands, on 3 different filter sizes.

It's online spreadsheet using Google's Free Docs app.

Please feel free to browse through it, use it, edit it, etc.

Cheers.

PS: Not affiliated to any stores.

That's great! I did a similar sheet a couple weeks ago when my brain was about to explode. What about adding in B&H and/or Adorama, since they are benchmarks for a lot of photo shopping?

Nightdiver13, good idea.
Please feel free to add in your research data, even if the date is older, I think it's still should be good as guidelines (at least to indicate if the store sells the brand/model of filter)

Cheers
