  <% @products.each do |product| %>

    <% cache ['entry', product] do %>

      <div class="entry">

        <%= image_tag(product.image_url) %>

        <h3><%= product.title %></h3>

        <%= sanitize(product.description) %>

        <div class="price_line">

          <span class="price"><%= number_to_currency(product.price) %></span>

          <%= button_to 'Add to Cart', line_items_path(product_id: product),
