The tabbed interface on the product details page is a fairly new feature is why some of the featured sites dont have that but you should be able to make a small change to the productdetails.ascx page to accomplish what you want.

1. On your server navigate to the \desktopmodules\smith.buynow folder
2. Open up productdetails.ascx in your editor
3. Go to line 183 and make these changes
   1. Set the visible property of the tab control (cc1:TabContainer) to false
   2. Move the lblDescription label field up so its outside of the tab control
   3. The code snippet with changes are highlighted in yellow below:

<tr align="left">
<td width="30px"></td>

<td runat="server" id="tdSpacer1" width="135px" visible="false"></td>

<td align="left" >
<asp:Label ID="lblDescription" runat="server" CssClass="SmithProdText" />
<cc1:TabContainer ID="TabContainer1" runat="server" ActiveTabIndex="0" CssClass="google" Width="600px" Visible="false" >

<cc1:TabPanel ID="TabPanel1" runat="server" HeaderText="Tab 1">

<ContentTemplate>
<div class="myTabs">
<asp:Label ID="lblDescription" runat="server" CssClass="SmithProdText" />
</div>
</ContentTemplate>
</cc1:TabPanel>

<cc1:TabPanel ID="TabPanel2" runat="server" HeaderText="Tab 2" Visible="false" >
<ContentTemplate>
<div class="myTabs">
<asp:Label ID="lblDesc2" runat="server" CssClass="SmithProdText" />
</div>
</ContentTemplate>
</cc1:TabPanel>

<cc1:TabPanel ID="TabPanel3" runat="server" HeaderText="Tab 3" Visible="false" >
<ContentTemplate>
<div class="myTabs">
<asp:Label ID="lblDesc3" runat="server" CssClass="SmithProdText" />
</div>
</ContentTemplate>
</cc1:TabPanel>

<cc1:TabPanel ID="TabPanel4" runat="server" HeaderText="Tab 4" Visible="false" >
<ContentTemplate>
<div class="myTabs">
<asp:Label ID="lblDesc4" runat="server" CssClass="SmithProdText" />
</div>
</ContentTemplate>
</cc1:TabPanel>

<cc1:TabPanel ID="TabPanel5" runat="server" HeaderText="Tab 5" Visible="false" >
<ContentTemplate>
<div class="myTabs">
<asp:Label ID="lblDesc5" runat="server" CssClass="SmithProdText" />
</div>
</ContentTemplate>
</cc1:TabPanel>

</cc1:TabContainer>
<%-- </div> --%>

</td>
</tr>

I too desire not to have the product description tab and the description area display. 

But, the productdetail.ascx does not seem to exist anymore on the trial version I just installed for evaluation.

Any help would be greatly appreciated.

Thanks.
