Long time since order to delivery

Prices are reasonable and the stuff is helpful. However... I've ordered and payed for 8 boxes on Monday and followed up by calling the company on Friday to hear if the product was shipped. The answer was that they just found out that they were out of stock for this product and had to produce them on the following day. The product was shipped on Monday the following week, but didn't arrive to Denmark(the neighbouring country) till next Monday, thereby ruining my plans to use the product for an event the weekend before and having to invest in alternative solution. I wonder what would happen if I didn't call them to check on the product status. Not a pleasant experience.
