Was the listing mislabeled? Because otherwise I'm not sure what your complaint is. You bought in bulk, without a bulk discount, and got a larger quantity of an item at a worse unit price. If your review was politely informing people that the price was bad, then you're not really reviewing the item, because you like the item.
I didn't buy it, there was no point. Buying items by the case online should be significantly cheaper than a single purchase at convenience retail.
The truth hurts I suppose. They should be interested in the information however, because it cost them and continues to cost them sales among the clueful.
