    To change the width of that space in a table using CSS you would use
table { 
    border-spacing: 10px;
    border-collapse: separate;
}
For more info see: Set cellpadding and cellspacing in CSS?
However as you haven't realy got tabular data and more of a list, I would use a list:
HTML
<ul class="products">
    <li>
        <h2>Abercrombie & Fitch</h2>
        <img src="http://dotacionesindustriales.net/images/4002%20Camisa%20Manga%20Corta%20Hombre-Oxford.jpg" />
        <div>
            <span class="price"><b>Price:</b> US $65</span>
            <span class="COD"><b>COD:</b> AE001 </span>
        </div>
    </li>
    <li>
        <h2>Hollister</h2>
        <img src="http://dotacionesindustriales.net/images/4002%20Camisa%20Manga%20Corta%20Hombre-Oxford.jpg" />
        <div>
            <span class="price"><b>Price:</b> US $65</span>
            <span class="COD"><b>COD:</b> AE001 </span>
        </div>
    </li>
    <!-- etc -->
</ul>
CSS
ul.products
{
    list-style:none;
    margin:0;
    padding:0;
}
.products li
{
    float:left;
    margin-right:1em; 
    margin-bottom:1.2em;
}
.products li img
{
    padding:6px;
    background-color: #e9f1f8;
    border: 1px solid #d3e6f6;
}
.products li h2
{
    color: #325A8C;
    font-size:16px;
    text-align:center;
    font-family:serif;
}
.products li div
{
    font-weight:bold;
}
.products li div .price
{
    color: #349031;
}
.products li div .COD
{
    color: #44403F;
    float:right;
    padding-right: 1.5em;
}
.products li div .price b, .products li div .COD b
{
    color:#000;
}
The most important part in regards to your original question is:
.products li
{
    float:left;
    margin-right:1em; /*Adjust this value to change the horizontal Spacing*/
    margin-bottom:1.2em;
}
Apart from being more semantic html, you get the added advantage of a fluid layout. If three products don't fit across the page it will adjust the layout accordingly. Similarly it will accomodate more if they will fit.
