Clicked on the site at 9.19am Sunday 6th
Verrry slow load up - I would have clicked the cross if I had been surfing.
Point 1 - You have a box in the right hand sidebar called 'Login/Logout' - what does that refer to? I assume it's something to do with the shopping cart stuff but it isn't exactly clear.
Point 2 - You have the posts set out as complete posts rather than teasers with the link to read more at the bottom. Using the shortened versions of posts might help in reducing the appearance of white space at the end of the 2 sidebars
Point 3 - The newsflash box runs yawningly slowly (at least it did for me) - less of a flash more of a dull glow
Point 4 - The Checkout page - The first bar seems to be too wide as the other 2 bars are pushed to the second line and are left justified. That may be because I had nothing in my cart but it could be a layout thing or just a different browser setting (I'm using FF version 3.6.13)
Point 5 - There is currently the option to leave a comment on the check out page. I can see the possibilities of this - return buyers could leave comments but they would have to be on the checkout page to leave a comment - not sure if that was meant to be.
Point 6 - There isn't a link to return to the posts / home page from the check out page. I had to reload the site to start reading again.
Point 7 - On each page in the footer links you have the 'Share This' button at the end of each page - is that warranted?
Suggestion 1 - I would have put the categories section at the top of the mid bar - that way visitors have instant ability to click on what they want.
Suggestion 2 - Does there have to be so many translation options? If so, then having that above Mike's testimonial would again make it easier for your foreign visitors (do people actually click on these things? Is that testable?)
If I have any further ideas then I'll be back

Good site all in all Howard - keep on trucking!
