OK- if you insist!
Not really a bad layout at all. Clean easy to read, and it flows well.
HOWEVER- while I have no clue what a "This sale is for three (3) copper Glow Head Gaskets for Cox .010 engines" is- some indication in the photo as the size/scale of the product would be helpful. A cent? A ruler? Some type of easily recognized comparison, For this item it may be redundant. For other items size matters.
The following "We accept Paypal - money orders, personal cheques and Interac email money transfers.
If mailing a M/O from outside of Canada, please ensure that it is an "International" version." may well, and most likely, will run afoul with eBay's accepted payment policies.
The INFO for Canadian residents must not be seen by eBay DOT COM users.
For the first two lines in the returns area- I would break the sentences after the commas, to make reading easier.
On this one I am going out on a limb.
The text within the boxes do not compress when I change my browser width. So, on a small screen, this would mean sliding side to side, which I find annoying. I am using a full size MAC right now- so I have no clue how a PC would respond to this issue. But, on a handheld device, this lack of scaling may be annoying, and possibly easily solved.
