It's really not that much? One lunch, a set of strings, etc.... There is a lot of work put into my presets. Each tone needed for each 'Artist' preset is included. Custom IRs and free updates too.
Most preset makers offer a pack of presets for $20 or more? It seems like a great deal, but you really only end up with a couple that appeal specifically to you? You have to buy the whole pack to get the one or two presets that you really wanted?
I have many 'Build Your Own Pack' discount codes that reduce the price dramatically when purchasing 4 or more presets at one time. You can get only the presets you want in a discounted 'Pack'. The larger the order, the larger the discount. From 35% off to 70% off. There are not enough Helix presets in my web-store yet to take advantage of the deeper discounts, but and '8pack' cuts the price in half.
