LOL I don't buy $80 jeans either.Those so rock! I think I saw those on a tv talk show last year and wanted to see how they felt in my hands - quality wise.
If you get them - please let us know how they are
ETA: a good pair of jeans cost $80?! Where are they shopping?! LOL I quite like my $20 old navy jeans - they're quite durable.
I guess its the cheesy late night infomercial factorSpandex/cotton jeans? What's weird about that? They've been selling them in stores for years. Personally I don't like them because the spandex attracts cat hair more than the 100% cotton ones do. YMMV.
