Comparing prices can be tricky, especially on the web. Most web site designs do not allow you to see the final cost until you have almost completed the checkout process. The word “almost” is important here, because it allows you to proceed through the checkout process far enough to see your final price, but not far enough to give up personal information, especially your payment information.
When filling in the required fields on various sites, you can use fictitious or imaginary information. Most web sites will only try to confirm the accuracy of your personal information in the very last stage, which is where you submit your payment information, and in this exercise, you have no intention of going that far, unless you have decided to buy. And then, hopefully it will be from us. 
Here are some random examples of price comparisons taken from the web:
In the above comparison, we used 2 bandanas to be as fair as possible to our competitors. Had we used a quantity of 3 bandanas (where our price drops from $10 to $8.33) for the comparison, the savings would have been significantly higher.
In conclusion, it is clear that the initial price you see for a product anywhere (not just the internet) rarely reflects your final cost. Best of all, you can use the above comparison technique on any website to avoid unpleasant surprises.
Of course, on ahhcool.com, the price you see for the quantity purchased, is in fact, your final cost. period.
