Hey store guys, you will sell a LOT more cosmetic options if you allow us to try them on before we buy them. Charge 1TP for a 5min version if you wish, but I know there are legions of players unwilling to spend the hundreds of TP on a hair colour/style without any real idea of what it looks like. Or at the very least provide a screenshot on the forums with a picture of 1 character from each race/sex combination wearing the item/option, so that we can see what it is in game, rather than on the tiny stylised icon.
After all, how often would you buy something out of a catalogue if there was a "No refunds, go <inclined plane around a rod> yourself" policy?
