You can use pretty much any Wordpress theme out there. Some free
themes specifically for phpBay sites are:
Limau Themes
WP Commerce Theme
Studio Press Theme
If you’re looking for something specific to your products, go to google
and search for “golf wordpress themes”. Replace “golf” with whatever
your site will feature. You should be able to find a handful of related
themes this way.
Personally I like using the theme called Thesis. Thesis has a lot
powerful tweaks built into the theme and it’s 3 column format makes
setting up an eBay store very easy and convenient. An example of a
Thesis store site is: http://www.cheaplaptopfinder.com There’s a lot of
options to set up different parts to your site as well as organize
product categories. The only downside is that it isn’t free.
Another nice one worth mentioning is Flexx Theme by iThemes.com.
Flexx theme is nice because it makes setting up a 3 column site with
a nice header and background very easy. No messing around with
code, just pick from the graphics which come in the package.
Whichever theme you go with, download the theme and put the files
on your desktop. Access your site with your FTP program and move
the files to: / wp-content/themes/
Log into your Wordpress Admin Panel. On the left side, there will be a
menu called “Appearance”. Click on it and activate the theme.
