I'm currently doing the Trials of Style week and whilst looking at the vendor it occurred to me that it would ne nice to be able to sort the vendor window by the cost of items, e.g. original order, highest to lowest, lowest to highest. my use case is that I'd like to be able to buy as many of the cheapest items as possible first to maximise use of tokens, before moving onto buying more expensive items, and it's easier to see what is cheapest when it's all grouped by price in the vendor window.

I would suggest changing the Filters drop down to "Filters & Sorting" and add a sorting section below the filters, allowing for sorting by various methods as noted above (highest to lowest, lowest to highest, reset etc). If there are multiple currencies on a vendor then have the option to group by currency first then apply highest to lowest, or run highest to lowest irrespective of currency type.

Hope that all makes sense.
