Hi Aquatix!
I took a quick look at the page, and i came up with a few points that imho could prove useful:
1.) You have the same title for many pages, like for example these:
www.cpap.net/manufacturers_cpaps/resmed/softgel.htm
www.cpap.net/manufacturers_cpaps/devilbiss/intellipap.htm
If there is no reason or big techical problematics in giving the pages their own titles it might be one thing to improve. Titles are not only invented to be stuffed with keywords, but they are one of the most important things that attract users to click on a search result. With a good title the #2 or #3 result might get higher clicks than the #1 search result.
Obviously titles are also a good place to put keywords in them. If you think your customer also search by brand or product name, cosider putting those in the title.
2.) Not really a SEO issue, but out of my experience in running ecommerce for 4 years, putting price tags on items increases their sales. You seem to have quite a few items with no price tags on them. Again, i dont know if there is a special reason not to put the pricetag there, but people are lazy by nature - if they find an other shop selling that product and they think the price is ok, they might not even ask you for a price.
EDIT HERE: I saw that resmed and respironics dont allow you to publish prices. If this is the case for the products i saw then it is my mistake to suggest this. You could inform customers about that on the pricelist page too tough.
3.) Whats with the three contact us boxes btw?
Example page: www.cpap.net/cpap_manufacturers_aeiomed.htm
You could consider moving the contact us box to the top below the "order today, ship out today" text. That way it would seem to be in a logical and easy to find place, at least that is what i think.
4.) On your contact page, consider making a contact form for your website. We use a contact form on our 200 to 400 visitors/day page, and people use it tens of times a day. A contact box could also be placed in the footer or the sidebar of the page with the title filled with something like "Question about AEIOmed Everest 2". This is convinient for the users since they are 0 clicks away from asking you something when they have a question.
5.) The footer texts/layout seems to be a little misplaced in IE8 / Vista 64. Not especially problematic, but could be a nice and easy fix for those days you feel like doing something easy.
6.) As a final note: Consider changing the header's "Americas premier discounter of cpaps since..." to a h1 text tag. I think that would give you a nice boost on cpaps as a keyword.
Generally the page seems to be easy to navigate and pretty responsive even from here in Finland. Keep up the good work!
