Relationship not returning fields

Hello everyone, Hope you can help me.

Windows 10 / Homestead Laravel 5.1

I have a ecommerce project i am building and here is my problem.

I have the following tables:

1. products

 Schema::create('products', function (Blueprint $table)
        {
            $table->increments('id');
            $table->string('status')->nullable();
            $table->string('availability')->default('Available');
            $table->string('slug')->nullable();
            $table->string('name')->nullable();
            $table->string('subtitle')->nullable();
            $table->string('manufacturer')->default('The Grace Company');
            $table->longText('details');
            $table->longText('description');

            $table->string('thumbnail')->nullable();
            $table->string('photo_album')->nullable();
            $table->dateTime('pubished_at')->index();
            $table->string('lang', 255);
            $table->timestamps();
            $table->softDeletes();
        });

1. prices

    Schema::create('prices', function (Blueprint $table)
        {
            $table->increments('id');
            $table->integer('product_id')->unsigned()->index();
            $table->decimal('price', 11, 2)->default('0.00');
            $table->string('model', 12)->nullable();
            $table->string('sku', 12)->default('000000');
            $table->string('upc', 13)->default('000000');
            $table->bigInteger('quantity')->default('99');
            $table->string('alt_details');
            $table->timestamps();
            $table->softDeletes();
            $table->engine = 'InnoDB';
            $table->foreign('product_id')->references('id')->on('products')->onUpdate('cascade')->onDelete('cascade');

        });

I have the following relationships product.php

    public function productPrice() {      return $this->hasMany(Price::class);    }

price.php

 public function product()    {        return $this->BelongsToMany(Product::class);    }

My problem is i cannot get my pricing to store to the alternate table pricing here is my controller store function.

public function store(Request $request) {
$this->validate($request, [
'name' => 'required',
]);
$dest = 'testing/';
$name  = str_random(4) . '_' . $request->file('thumbnail')->getClientOriginalName();
$request->file('thumbnail')->move($dest, $name);
$product = $request->all();
$product['thumbnail'] = '/' . $dest . $name;
$product = Product::create($product);

if ($request->has('productPrices')) {
foreach ($request->productPrices as $price){
if (!empty($price['price'])){
$price = Price::create($request->all());
}
}
}

foreach ($request->categories as $category_id)
        {
            CategoryProduct::create(['category_id' => $category_id, 'product_id' => $product->id]);
        }

FlashAlert()->success('Success!', 'The Product Was Successfully Added');

        return \Redirect(getLang() . '/admin/products');
}

I can store the product just fine but i cannot get it to store the product pricing table data.

any help would be greatly appreciated.
