Hi merbay,
To remove "See Details"...
open up skin1/customer/main/products.tpl and {* comment out *}
Code:
<a href="product.php?productid={$products[product].productid}&cat={$cat}&page={$navigation_page}{if $featured eq 'Y'}&featured{/if}">{$lng.lbl_see_details}</a>
To remove "save x%"...
Again in products.tpl locate and comment out...
Code:
{$lng.lbl_save_price} {$discount}%
There doesn't appear to be anything that can remove SKU either so if you've already commented it out. It should be okay.
Hope this helps.
