When shopping on Amazon, they will often show the price as a range. This is common for clothing which comes in many different sizes and color combinations. Often only a couple of variations will come in at the low price. It might be a variation that is not selling well. Here is an example:
Maybe you will get lucky and the variation you want to buy is at the lowest price of the range. Instead of sorting through every possible combination, you just need to type the ASIN (Amazon Standard Identification Number) into the box below and click "GO!". This will open a window directly to the product's offer listing page. I've detailed below how to find the ASIN and how to find the variation with the lowest price.
How to find the ASIN Number
Find the ASIN (combination of 10 letters and number) in the address bar. It appears immediately after "dp" in the address.
Finding the Lowest Price in the Range
Once you are on the page, there will be buttons for the different options. As each button is clicked, the price list will update below. To show the lowest prices of all the variations, the "Lowest Offer for Each" button for each option needs to be clicked (numbered 1 and 2 in the picture below). When all the "Lowest Offer for Each" have been clicked, the price list will show the cheapest of all variations.
This interface will only be shown when you are on a computer. A phone browser will not show it.
