It is very frustrating to open the box and see the baggie of hardware had spilled into the box and was missing 1 out of the 4 bolts and 1 out of the 4 washers. The shipping carton was sealed all around with tape so this error occurred NOT in shipping.  
Not a big deal...unless one expects a product to ship complete. 
After a trip to the hardware store where my gas cost more than the $ .88 for the parts, we have an umbrella.
BUMMED!
