For anyone curious about the Pro version of Delftship, I think it’s somewhat irritating that the prices for extensions aren’t available on the site. Presumably they are all much the same price if purchased one at a time, and perhaps there is a discount if they are all purchased at once. These prices will already be known by the vendor, so not stating them clearly seems a bit silly.
It’s rather like “You want to buy this? Ok, well the price is a secret. I’m not telling.” 😛
How about just whipping up a short list of prices and adding them to the relevant pages? That way there’s no need for people to mess around with emails. Should make things easier.
