It is quite common for people to find the under $10 or under $20 wines in red or white categories. While there is no industry-recognized benchmark on which wines would be considered cheap or which ones would be considered premium, it is generally assumed that the under $10 or $20 wines are cheap. Red wines are produced and sold a lot more than white wines in Australia. Therefore, there are more cheap red wines available in market than the white ones. With online wine stores, this search for the cheap white wines is rendered a lot easy.
An online wine shop would provide the categories of red, white and other wines separately. This would ease the navigation to find just the white wines. However, there could be a number of such wines listed under this category, of different price ranges. You will have to use the filters to find the under 10 or 20 white wines which will refine the search further and show only the limited number of inventory to make it easy to search for these.
Another place to look for the cheap white wines is the wine offers page. Whether there is a separate categorization of red, white or other types of wines within this page or not is what will define the ease of searching. If there are many offers, then this categorization helps visitors looking for low-cost wines. But, if there are not many wine deals on offer, then this might not be done. In the latter case, visitors will have to sort out the economical white wines from other types of wines. This might take a little more time but is worth doing it since the wines can be really cheap if bought on a good deal.
