Bedding

The very definition of frustration: buying a new "King-sized" duvet cover, and finding it is way bigger than your existing "King-sized" duvet.  So I'm forced into either buying a new duvet, or discarding my new duvet cover.  It is absolutely ridiculous that there no standard bedding size - the range of dimensions for "King-sized" is extraordinary.  I guess different brands have different dimensions, forcing you to buy more of their products.  And sure enough, I went and ordered a new (and expensive) duvet from the same company who I bought my new (and expensive) duvet cover from.  What a racket.
