Products in page via sku

I need to retrieve multiple products from woocommerce on my pages (pages that support tags, category etc). So far I succeed to retrive just one product, but now I need to do something more complicated.

for example:

I have a page A with tag “x” and “y”, and product in woocommerce B with sku “x” and product C with sku “y” (x and Y the same as the page A). Here’s is my code, code that retrieve me just product of one tag, it dublicate me the result on page.

<?php
$posttags = get_the_tags();
$count=0;
if ($posttags) {
foreach($posttags as $tag) {
$count++;
if (1 == $count) {
$args = array( 'post_type' => 'product', 'posts_per_page' => 1,'product_tag' => "' . $tag->slug .'" );
}
}
}
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post(); global $product; ?>
<div style="clear: both;
width: 100%;
max-width: 721px;
margin-bottom: 5px;
float: left;
background-color: #D7F1FF;
border: 1px solid #449BC7;
padding-top: 4px;
padding-left: 5px;"><span class="teaser-image-small"><img title="image title" alt="thumb image" class="wp-post-image" src="<?=wp_get_attachment_url( get_post_thumbnail_id() ); ?>" style="width:30px;"></span>
<span style="
font-size: 16px;
vertical-align: 15px;
">Cump?r? acum <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a> la pre?ul de doar
<?php echo $product->get_price_html(); ?>
<!-- <a href="<?php the_permalink(); ?>?add-to-cart=<?php global $post; echo $post->ID; ?>">Cump?r? acum</a> --></span></div>
<?php endwhile; wp_reset_query(); ?>
<?php
$posttags = get_the_tags();
$count=0;
if ($posttags) {
  foreach($posttags as $tag) {
    $count++;
    if (2 == $count) {
$args = array( 'post_type' => 'product', 'posts_per_page' => 1,'product_tag' => "' . $tag->slug .'" );
}
}
}
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post(); global $product; ?>
<div style="clear: both;
width: 100%;
max-width: 721px;
margin-bottom: 5px;
float: left;
background-color: #D7F1FF;
border: 1px solid #449BC7;
padding-top: 4px;
padding-left: 5px;"><span class="teaser-image-small"><img title="image title" alt="thumb image" class="wp-post-image" src="<?=wp_get_attachment_url( get_post_thumbnail_id() ); ?>" style="width:30px;"></span>
<span style="

<?php echo $product->get_price_html(); ?>
<!-- <a href="<?php the_permalink(); ?>?add-to-cart=<?php global $post; echo $post->ID; ?>">Cump?r? acum</a> --></span></div>
<?php endwhile; wp_reset_query(); ?>
