Trying to set up a POC for a Vendr shop with an external product catalog.

The ProductSnapshot looks like this

public class Product : IProductSnapshot
{
    public int Id { get; set; }
    public string ProductReference => Id.ToString();
    public string Sku => Id.ToString();
    public string UrlSegment => string.Format("{0}-{1}", Name, Sku).ToSafeAlias();
    public Guid StoreId => new Guid("c7624842-d284-464b-aee0-b99e42c1993b"); // hardcoded for speed :)
    public IEnumerable<ProductPrice> Prices { get; set; }
    public IDictionary<string, string> Properties
    {
        get
        {
            var dict = new Dictionary<string, string>();
            dict.Add("Category", Category.Name);
            dict.Add("Description", Description);
            return dict;
        }
    }
    public Category Category { get; set; }
    public string Name { get; set; }
    public string Description { get; set; }
    public string ImageUrl { get; set; }

    public Guid? TaxClassId => new Guid("6d12d936-f58a-44ef-a4ee-3b7c60b3d22b"); // hardcoded for speed :)

    public bool IsGiftCard => false;
}

And is created from a CSV like this

            int.TryParse(x[0], out int id);
            decimal.TryParse(x[6].Replace(".", "").Replace(" DKK", ""), out decimal price);

            var category = categories.FirstOrDefault(c => c.Name.InvariantEquals(x[1]));

            var prices = new List<ProductPrice>();
            prices.Add(new ProductPrice(price, new Guid("0beb35b4-f907-49c4-b114-8aecd7f7925e")));

            return new Product()
            {
                Id = id,
                Category = category,
                Name = x[2],
                Prices = prices,
                ImageUrl = x[8]
            };

And the product adapter looks like this

    public IProductSnapshot GetProductSnapshot(string productReference, string languageIsoCode)
    {
        return ProductRepo.GetProduct(productReference);
    }

    public string GetProductReference(Guid storeId, string sku)
    {
        // SKU and ProductReference is the same in the POC, so just return SKU
        return sku;
    }

When I add the product to the cart, I do it like this:

            using (var uow = _unitOfWorkProvider.Create())
            {
                var store = CurrentPage.GetStore();
                var product = ProductRepo.GetProduct(postModel.ProductReference);

                var order = _sessionManager.GetOrCreateCurrentOrder(store.Id)
                    .AsWritable(uow);

                order = order.AddProduct(product, postModel.Quantity);

                _orderService.SaveOrder(order);

                uow.Complete();
            }

It then breaks and gives the message Can't add a Product to an Order where there is no price for the Order currency..

I have verified that the currency on the product price is the same as the currency on the order.

Am I missing something on the ProductSnapshot?
