Thin Paper from Clark Photo Labs

Hi,

We just used Clark Photo Labs for the first time to develop our digital
photos using their web site.

We received our photos and the quality of the images is fine, but the
photo paper feels very thin compared to other places we have used
(Ofoto, Kodak, Clubphoto, etc.).

Has anyone else noticed this? We are unsure if this thinner paper will
matter at all as these photos will be put in an album, but it suprised
us that it feels so much cheaper.
