Does this constitute bad usability?

While on swisscolony.com I noticed their Fruit Spread Sampler came in two varieties: box of 9 and box of 18. However, the product description states “Gift includes six tempting flavors—strawberry, orange marmalade, peach, raspberry, grape and blueberry”. My question is if there are six flavors and 9 jars which three flavors get added twice? Do you believe this ambiguity might cause a ‘few’ people to decide not to buy?
