Price in order-details.php is different a price in shop

The price product is 300 imagen here

But in order-details.php and email notification the price is 3 imagen here

I printed in “foreach($order->get_items() as $item) :” the var print_r($item) the result is

Array ( [id] => 132 [variation_id] => [name] => Snack de Manzana Roja [qty] => 10 [item_meta] => Array ( ) [line_subtotal] => 3 [line_subtotal_tax] => [line_total] => 3 [line_tax] => [tax_class] => )
